Webb16 sep. 2016 · Here, tan(θ 2) = sinθ = 2tan(θ 2) 1 + tan2(θ 2) So, tan( θ 2)((1 + tan2( θ 2) − 2) = 0. And so, tan(θ 2) = 0 gives θ 2 = kπ,k = 0,1,2,3,.. the other factor = 0 gives# tan^ … WebbCancel the common factor of sin(θ) sin ( θ). Tap for more steps... Multiply 1 cos(θ) 1 cos ( θ) by 1 cos(θ) 1 cos ( θ). Raise cos(θ) cos ( θ) to the power of 1 1. Raise cos(θ) cos ( θ) to the power of 1 1. Use the power rule aman = am+n a m a n = a m + n to combine exponents. Simplify the expression.
