Step 1 :We are given the function \(f(x)=7 \csc ^{2} x\). We need to find all antiderivatives of this function.
Step 2 :The antiderivative of a function is the integral of that function. So, we need to find the integral of \(f(x)=7 \csc ^{2} x\).
Step 3 :The integral of \(\csc ^{2} x\) is \(-\cot x\). Therefore, the integral of \(7 \csc ^{2} x\) is \(-7\cot x\).
Step 4 :However, the integral also includes a constant of integration, which we'll denote as \(C\). So the most general antiderivative of \(f(x)\) is \(F(x) = -7\cot x + C\).
Step 5 :We can check this by taking the derivative of \(F(x)\) and seeing if we get \(f(x)\) back.
Step 6 :Taking the derivative of \(F(x) = -7\cot x + C\), we get \(f(x) = 7 \csc ^{2} x\). This confirms that \(F(x)\) is an antiderivative of \(f(x)\).
Step 7 :\(\boxed{F(x) = -7\cot x + C}\) is the final answer, where \(C\) is an arbitrary constant.
