Can someone tell me what is the integral of
(-39240)(9-x^2)^(1/2)
(-39240)(9-x^2)^(1/2)
The first step is to use the power rule to rewrite the expression as (-39240)(9-x^2)^(1/2) = (-39240)(9)^(1/2)(1-x^2)^(1/2).
To integrate the expression, use the substitution method by letting u = 1-x^2. This will result in the integral becoming (-39240)(9)^(1/2)∫u^(1/2) du.
After using the substitution method and rewriting the integral as (-39240)(9)^(1/2)∫u^(1/2) du, you can use the power rule for integrals to solve for the integral.
To use the power rule, add 1 to the exponent and divide by the new exponent. This will result in (-39240)(9)^(1/2)∫u^(1/2) du = (-39240)(9)^(1/2)((u^(3/2))/(3/2)) + C.
The final step is to substitute back in the original variable, u = 1-x^2, to get the final answer of (-39240)(9)^(1/2)((1-x^2)^(3/2))/(3/2) + C.
