find the derivative of cos x To find the derivative of cos x we take the limiting value as x approaches x h To simplify this we set x x h and we want to take the limiting value as h approaches 0 We are going to use certain trigonometry formulas to determine the derivative of cos x The formulas are cos A B cos A cos B sin A sin B
Transcript Ex 12 2 10 Find the derivative of cos x from first principle Let f x cos x We need to find f x We know that f x 0 Here f x cos x So f x h cos x h Putting values f x lim h 0 We can find the derivatives of sin x and cos x by using the definition of derivative and the limit formulas found earlier The results are dfrac d dx big sin x big cos x quad text and quad dfrac d dx big cos x big sin x
