Identify which of the following functions require chain rule application to obtain their derivatives: a)y=ln(cos(x)) b)y=3x-ln7 c)y=(arcsen(x))(tanx)

2. Find the derivative of y in each case. (a) y = sin³x + cos³x (b) y = tan² (x³) (c) y 4 sec(5x)

2. Computing Derivatives; Compute each derivative using the derivative rules: d cos-"(1+ x²) + tan (a) dx -'(1 + c*) e3x² d (b) (cos(1+x²) + tan'+e3=² da d (c) (1+ x² + ln[1 +x + sin¬'(1 + x)]) dx
