Calculate the following integrals. if the answer requires a constant of integration, enter it as c. you may enter a symbolic answer for any of the following (for some, that means a formula in terms of x, for others, that means a formula for the exact answer). for those integrals that have a numerical answer, you may enter the numerical value of the integral as a decimal, but be sure to enter sufficiently many decimal places (enter as many as you can). int 5/x^4 text( )dx = 5(-1/3)x^(-3)+c click here to preview your answer. correct: your answer is correct. int_0^1 x^3 text( ) dx = (1/4) click here to preview your answer. correct: your answer is correct. int_2^5 \(5/x+5 sqrt(x)\) text( ) dx = click here to preview your answer. int e^(-x/4) text( )dx = click here to preview your answer. int_3^4 \(5 e^(-x/5) - 4\) text( )dx = click here to preview your answer. int -7/sqrt(x) text( )dx = click here to preview your answer. int (5-x)/x^5 text( )dx = click here to preview your answer.
