WebFUN‑3.A.4 (EK) Google Classroom. Proving that the derivative of sin (x) is cos (x) and that the derivative of cos (x) is -sin (x). The trigonometric functions \sin (x) sin(x) and \cos (x) cos(x) play a significant role in calculus. These are their derivatives: WebYes you are correct that the derivative of -sinx is -cosx. d/dx means "the derivative of, with respect to x". So for example, d/dx (-sinx) = -cosx. ( 16 votes) Eloísa Lira 5 years ago At 1:09 , Why I can't just write the derivative of the last one putting 2 before it ? Like 2 (pi/cubic square of x) • ( 3 votes) Mateusz Jastrzębski 5 years ago
