Find the exact values for trigonometric ratios for the angle θ = 135 ∘. Find the value of sin ( 135 ∘) as follows. Find the exact values of the six trigonometic functions for the following angle. 135° = sin 135° (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.Trigonometry. Evaluate tan (135 degrees ) tan (135°) tan ( 135 °) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant. −tan(45) - tan ( 45) The exact value of tan(45) tan ( 45) is 1 1. −1⋅1 - 1 ⋅ 1.Use a diagram to explain why {eq}\sin(135) = \sin (45) {/eq}, but {eq}\cos (135) \neq \cos (45) {/eq}. Sine and Cosine on the Unit Circle: The trigonometric functions sine and cosine are introduced in terms of the ratios of sides in a right triangle, but they can be defined more broadly than that.In addition to degrees, the measure of an angle can be described in radians. See Example. To convert between degrees and radians, use the proportion \(\frac{θ}{180}=\frac{θ^R}{π}\). See Example and Example. Two angles that have the same terminal side are called coterminal angles. We can find coterminal angles by adding or …3π/4 * 180/π = 135 degrees So our angle measures 135 degrees. Now let's determine which quadrant this angle lies in. A positive angle in the second quadrant will have a cosine value that is negative and a sine value that is positive. Using the unit circle, we can see that our angle of 135 degrees is in the second quadrant.3π/4 * 180/π = 135 degrees So our angle measures 135 degrees. Now let's determine which quadrant this angle lies in. A positive angle in the second quadrant will have a cosine value that is negative and a sine value that is positive. Using the unit circle, we can see that our angle of 135 degrees is in the second quadrant.Find the value of cos 135 °: Since, cos 135 ° = cos (90 ° + 45 °) Which clearly lies in the 2 n d quadrant, where cos is negative. since c o s (90 ° + θ) =-sin θ. Thus, cos 135 ° = cos (90 ° + 45 °) =-sin 45 ° sin 45 ° = 1 2 =-1 2. Hence, the value of cos 135 ° is -1 2..
