WebAnswer: Hence, we have established the identity cot2x = (1/2)(cotx - tanx) Example 2: Evaluate the derivative of cot2x. Solution: To determine the derivative of cot2x, we will use the chain rule method of differentiation. We know that the derivative of cotx is -cosec 2 x and the derivative of 2x is 2. Therefore, we have Webtan2(x) ⋅sin2(x) tan 2 ( x) ⋅ sin 2 ( x) Because the two sides have been shown to be equivalent, the equation is an identity. tan2(x) ⋅sin2(x) = tan2 (x)−sin2 (x) tan 2 ( x) ⋅ sin 2 ( x) = tan 2 ( x) - sin 2 ( x) is an identity
WebAug 7, 2013 · Secondly, the identity is tan²θ + 1 = sec²θ, not tan²θ - 1. Maybe this proof will be easier to follow: tan²θ + 1 = sin²θ/cos²θ + 1 = sin²θ/cos²θ + cos²θ/cos²θ = (sin²θ + cos²θ)/cos²θ //sin²θ + cos²θ = … WebMar 7, 2016 · It is. ∫(tanx)2dx = ∫ sin2x cos2x dx = ∫ 1 −cos2x cos2x dx = ∫ 1 cos2x dx − ∫1dx = tanx − x + c. where c is the integration constant.
