Webb31 juli 2024 · 1=1−cosec(A)+cot(A)⇒cosec(A)=cot(A) [Eq.2] Well, it certainly doesn’t look like your equation is true for all values of A! So, for what values of A is your equation … WebbRHS = 1+cosA1−cosA× 1−cosA1−cosA= 1−cos 2A(1−cos) 2= sin 2A(cos 2A−1) 2LHS =(cotA−cosecA) 2=( sinAcosA− sinA1) 2sin 2A(cosA−1) 2= RHS∴ Hence, proved. Webb= ( cot A + cos e c A) - ( cos e c 2 A - cot 2 A) cot A - cos e c A + 1 = ( cot A + cos e c A) ( 1 - ( cos e c A - cot A)) cot A - cos e c A + 1 = cot A + cosec A = cos A sin A + 1 sin A = cos A … speedy 75019
