The simplest form of (1-cos^2a)(1+cot^2a) is 1

Step-by-step explanation:

Given expression is (1-cos^2a)(1+cot^2a)

To solve the given expression into simplest form :

  • (1-cos^2a)(1+cot^2a)
  • =sin^2a(cosec^2a) ( by using the identity sin^2x+cos^2x=1 then implies that 1-cos^2x=sin^2x and cose^2x-cot^2x=1 which implies that 1+cot^2x=cosec^2x )
  • =sin^2a(\frac{1}{sin^2a})  ( by using the identity cosec^2x=\frac{1}{sin^2x} )
  • =1
  • Therefore the given expression becomes simplest from to (1-cos^2a)(1+cot^2a)=1

Therefore the simplest form of (1-cos^2a)(1+cot^2a)

is 1

Therefore the given expression implies (1-cos^2a)(1+cot^2a)=1
