cos (135°) cos ( 135 °) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. −cos(45) - cos ( 45) The exact value of cos(45) cos ( 45) is √2 2 2 2. − √2 2 - 2 2. The result can be shown in multiple forms.Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more.Learn the values for these. The truth is there's no easy way to compute the tan/sin/cos of an angle without the calculator. The best you could do is use a Maclaurin series. That would involve having to convert from degrees in to radians. If you're unfamiliar with the concept of radians then for this example 45 degrees = pi/4 as in pi/4=3.1415 ...For sin 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 150° value = 1/2 or 0.5. Since the sine function is a periodic function, we can represent sin 150° as, sin 150 degrees = sin (150° + n × 360°), n ∈ Z. ⇒ sin 150° = sin 510° = sin 870 ...

Answer. Verified. 412.2k + views. Hint: In this question, we first need to write \ [ { {135}^ {\circ }}\] as the sum of the known angles and convert it accordingly by using the trigonometric ratios of compound angles formula. Then we can get the value from the trigonometric ratios of some standard angles. Complete step-by-step answer:Use integers or decimals for any numbers in the expression.) O A. cos 2 135° - sin 2135º = o = COS O OB. cos 2 135° - sin 2135º = tan OC. cos 2 135° - sin 2 135º = sin The exact value of the expression is (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Rationalize the denominator.)sin45° = √ (2)/2. sin 45° = √ (2)/2. sin 45 degrees = √ (2)/2. The sin of 45 degrees is √ (2)/2, the same as sin of 45 degrees in radians. To obtain 45 degrees in radian multiply 45° by π / 180° = 1/4 π. Sin 45degrees = sin (1/4 × π). Our results of sin45° have been rounded to five decimal places. If you want sine 45° with ...From the airport and airport lounge, here's what it is like to fly Singapore Airlines Airbus A350 Business Class including dining, seating, and service. We may be compensated when ...Method 2. By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. As given, sin (90° +30°) = cos 30°. It means that sin 120° = cos 30°. We know that the value of cos 30 degrees is √3/2.

Find the exact value of each expression(no calculator): 1) sin^2(30 degrees) + 1/ sec^2(20 degrees) Find the indicated value. tan(405 degrees) Find the exact value of the expression. sin 30 degrees cos 60 degrees; Find the exact value of the expression. sin 165 degrees cos 45 degrees; Find the exact value of the expression. sin 45 degrees cos ...And since we’re working with sin in our question, our value will be positive. the related acute angle of 135 degrees with reference to the x axis is 180-135= 45 degrees. So we know sin(135) is positive and that it has the same value as our reference angle 45 degrees. Therefore, we can write Sin(135)= sin(45)= sqrt(2)/2 ….

Arcsine is an inverse of the sine function. In other words, it helps to find the angle of a triangle that has a known value of sine: arcsin (x) = y iff x = sin (y) As sine's codomain for real numbers is [−1, 1] , we can only calculate arcsine for numbers in that interval. This means that the domain of arcsin (for real results) is -1 ≤ x ≤ 1.Here's the best way to solve it. Without using a calculator, compute the sine and cosine of 135° by using the reference angle. What is the reference angle? degrees. In what quadrant is the given angle? (answer 1, 2, 3, or 4) sin (135°) = cos (135) = ("NO DECIMALS Type sqrt (2) for 2 and sqrt (3) for 13.)For sin 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 45° value = 1/√2 or 0.7071067. . . Since the sine function is a periodic function, we can represent sin 45° as, sin 45 degrees = sin (45° + n × 360°), n ∈ Z. ⇒ sin 45° = sin 405° = sin 765 ...
