$$\int sec^2x \tan^2x dx = tan^2x 2\int \sec^2x \tan^2x dx$$ You can move the $ 2\int \sec^2x \tan^2x dx$ to the left hand side of the equation by addition $$\int \sec^2x \tan^2x dx 2\int \sec^2x \tan^2x dx= tan^2x c, c\in\mathbb{R}$$ Note that once we have a side without an integral on it you need to include a constant of integrationTan^2xtan^2y=sec^2xsec^2y and, how do you factor and simplify, cscx(sin^2xcos^2xtanx)/sinxcosx Calculus Solve The posistion of a particle moving along a coordinate line is s=sqrt(54t), with s in meters and t in seconds Find the particle's velocity at t=1 sec A) 2/3 m/sec0218 · (1 tan^2x) (1cot^2x)> 2 2 =) sec^2x cosec^2x >4 hence proved New questions in Math the length of a rectangle field is 12 and breadth is 400 meter find the ratio of length and breadth What is 16of Rs 60?
