WebOct 3, 2024 · This video shows how to find the exact trig values of 90 degrees. WebFor cosec 90 degrees, the angle 90° lies on the positive y-axis. Thus cosec 90° value = 1. Since the cosecant function is a periodic function, we can represent cosec 90° as, cosec 90 degrees = cosec (90° + n × 360°), n ∈ Z. ⇒ cosec 90° = cosec 450° = cosec 810°, and so on. Note: Since, cosecant is an odd function, the value of ...

WebThe angles that they're picking are ones that can be made by adding angles that are easy to remember, namely pi/6, pi/4, pi/3, and pi/2 (30, 45, 60, and 90, respectively) and their multiples. You can use angle addition to quickly find the trig values of, say, 75 degrees, since it's easy to see that 45+30=75.

WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
