Detail solution
-
Let .
-
Apply the power rule: goes to
-
Then, apply the chain rule. Multiply by :
-
The derivative of cosine is negative sine:
The result of the chain rule is:
The answer is:
The first derivative

$$- 100 \sin{\left(x \right)} \cos^{99}{\left(x \right)}$$
The second derivative
[src]
98 / 2 2 \
100*cos (x)*\- cos (x) + 99*sin (x)/
$$100 \left(99 \sin^{2}{\left(x \right)} - \cos^{2}{\left(x \right)}\right) \cos^{98}{\left(x \right)}$$
The third derivative
[src]
97 / 2 2 \
200*cos (x)*\- 4851*sin (x) + 149*cos (x)/*sin(x)
$$200 \left(- 4851 \sin^{2}{\left(x \right)} + 149 \cos^{2}{\left(x \right)}\right) \sin{\left(x \right)} \cos^{97}{\left(x \right)}$$
