Question

sinx+secx.cosx+cosecx darivative​

Answer 1

Answer:

sinx+ secx. cos x +cosecx

= d/dx( sinx+ sec x. cos x +cosec x)

= d/dx(sin x +1/cos x. cos x + cosec x)

= d/dx( sin x + 1 + cosec x )

= d/dx sin x + 0 + d /dx(cosec x)

= cosx + (- cosec x. cot x)

= cos x - cosec x. cot x

= cos x - cos x .cosec^2 x

= cos x ( 1 - cosec ^2 x)
