Find the derivative of a trigonometric function.

**Problem 45:**

Find the function \( g(t) = \sqrt[4]{t} + 6 \csc t \).

This mathematical expression defines a function \( g(t) \) which is the sum of two terms:

1. **\(\sqrt[4]{t}\):** This represents the fourth root of \( t \), which is a type of radical expression.

2. **\(6 \csc t\):** This term is 6 times the cosecant of \( t \), where cosecant is the trigonometric function, the reciprocal of sine. 

This function may be studied in a context involving analysis or graphing of equations with both algebraic and trigonometric components.

Expert Solution
Step 1

We write g(t) using exponent first, then differentiate both sides with respect to t.

g(t)=t4+6csc(t)g(t)=t14+6csc(t)g'(t)=ddtt14+ddt(6csc(t))g'(t)=14t14-1+6(-csc(t)cot(t))g'(t)=14t-34-6csc(t)cot(t)g'(t)=14t34-6csc(t)cot(t)
