WebJul 12, 2024 · To find the angle theta in degrees in a right triangle if the tan θ = 1.7, follow these steps: Isolate the trig function on one side and move everything else to the other. … WebHow do you use a double angle identity to find the exact value of each expression? You 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
Web1.5 sin θ = cos θ. Squaring both sides we have. 2.25 sin 2 θ = cos 2 θ. and since cos 2 θ = 1 − sin 2 θ we have. 2.25 sin 2 θ = 1 − sin 2 θ 2.25 sin 2 θ + sin 2 θ = 1 3.25 sin 2 θ = 1. From this, you can figure out the value of sin 2 θ. Taking square roots will tell you something about the absolute value of sin θ.
