Chapter 6.2, Problem 56E

Hi I was wondering if you could walk me through a problem? The integral of x3*sqrt(x2+25)dx. Thanks!

Evaluate the integral sec(theta)/sec(theta)-tan(theta) d(theta) A. sec2(theta) - tan(theta) + CB. tan(theta) + sec(theta) + CC. tan2(theta) + sec(theta) + C D. tan (theta) - sec(theta) +C please let me know if you need a picture. I wish i was able to format the integral better here.  sec(x)/sec(x)-tan(x) dx (this is to help if you don't understand the theta input)

Evaluate each integral in Exercises 47-50 by reducing the improper fraction and using a substitution (if necessary) to reduce it to standard form. 47. 48. -dx 49. de 2x3 dx 50.472-737 de 2x + +1

can i get step by step help please

What have you learned in evaluating integrals?

Please answer all steps for the problem to solve the whole problem. Be clear with steps, thanks!!

Integral of 2xln(1+x)

Explain how to evaluate a definite integral using area -what area should be shaded -where the area is relative to the x-axis -what shapes could be involved -what could make the value of an integral equal a negative value -what could make the value of an integral equal to zero  -what is the order of the endpoints on the integral and what happens if they are reversed.

please show steps so i can understand, i got a very long answer and dont think its correct
