• ### How does the derivative of f(t) = t(tan(t) equal tan(t)+t(1+tan(t)^2) ?

A question asks to differentiate f(t) = t(tan(t)Answer key gives: tan(t)+t*(1+tan(t)^2)Please explain how to arrive at that answer; what rules of derivatives are used?I use the product rule and I arrive at t(sec^2t) + tan(t)(1)is this not correct?Does sec^2tequal(1+(tan(t))^2) perhaps?Therefore would have have:t * ( 1+tan^2(t) )+ tan(t)??Thanks
