derivative of f(x)=t^4cos(t)

derivative of

f (x) = t^{4} cos (t)

\frac{d t}{d x} = 0

Solution steps

f (x) = t^{4} cos (t)

Treat

t

t (x)

Differentiate both sides:

0 = 4 cos (t) t^{3} \frac{d t}{d x} - sin (t) \frac{d t}{d x} t^{4}

Isolate

\frac{d t}{d x} : \frac{d t}{d x} = 0

\frac{d t}{d x} = 0

\int_{5}^{9} x^{2} d x

x \to 2 lim (2 x + 6)

5 - x^{2}, 17 - 7 x

\int c t d t

x \to π lim (cos (x))
