Question

Sederhanakanlah cot x (tan kuadrat x + 1)

Answer 1

Cot x (tan^2 x + 1)= cot x(sec^2 x)
= cot x(1/cos^2x)
= (cos x/sin x)(1/cos^2 x)
= (1/sinx)(1/cosx)
= 1/ sinx.cosx

Answer 2

Cot x (tan^2 x + 1)= cot x(sec^2 x)
= cot x(1/cos^2x) = (cos x/sin x)(1/cos^2 x)
= (1/sinx)(1/cosx) = 1/ sinx.cosx
maaf kalo salah
