WebNov 21, 2024 · See explanation. It depends on what derivative you want. If you want dy/(dt) and (dx)/dt, simply differentiate the x and y functions with respect to t, the same way you would differentiate a function f(x) with respect to x. x(t)= e^(1-t) -> dx/dt = -e^(1-t) y(t) = tan^2(t) = (tan t)(tan t) -> dy/dt = 2tan(t)d/dt(tan t) = (2 tan t)/(sec^2(t) If you specifically … WebNov 23, 2015 · Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site WebEvaluate the Integral integral of sec(t)(sec(t)+tan(t)) with respect to t.
