Differentiate with respect to x:tan3 x

1.	Differentiate with respect to x:tan3 x
Answer» Chain rule: If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx Let y = tan³ x dy/dx = 3 tan² x [d/dx (tan x)] = 3 tan² x sec²x

Answer»

Chain rule:

If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx

Let y = tan³ x

dy/dx = 3 tan² x [d/dx (tan x)]

= 3 tan² x sec²x
