Q54 of 354 Page 11

Differentiate the following functions with respect to x:

eaxsec(x)tan(2x)

Let y = eaxsec(x)tan(2x)


On differentiating y with respect to x, we get




We have (uv)’ = vu’ + uv’ (product rule)




We will use the product rule once again.



We know, and




However,






Thus,
