Первообразные функции f (x). F (x) = 3tgx F (x) = 5ctgx F (x) = 3/cos в квадрате x F (x) = - 5/sin в квадрате x

f (x) = F' (x)

F (x) = 3tgx f (x) = 3/cos²x

F (x) = 5ctgx f (x) = - 5/sin²x

F (x) = 3/cos²x = 3· (cosx) ² f (x) = 3· (-2) · (cosx) ⁻³· (-sinx) = 6sinx/cos³x

F (x) = - 5/sin²x = - 5· (sinx) ⁻² f (x) = - 5· (-2) · (sinx) ⁻³·cosx = 10cosx/sin³x
