example problems and soloution of trigonometric integral

Department of Chemcial Engineering - Good night everybody, how are you? hopefully everything in healthy condition:). Ok, in this moment mr.Chem-eng21 want to continue lesson of calculus about integral, and this moment i want to share example problem and solution of trigonometric integral. Yap TRIGONOMETRY, i think trigonometric lesson is one of lesson that difficult for me, but we must try, try and try, so we will can do solving of problem. if we compared with other lesson in calculus, trigonometry is the most difficult, in my opinion. But all of lesson in calculus is easy, if we want to learn in earnest. Ok friend, pay attention to and understand the following  sample question!

• ∫(sin3x + 4cos2x)dx

 = ∫sin 3xdx + 4∫cos2xdx

 =  − 13cos3x + 4.12sin2x + C

 =  − 13cos3x + 2sin2x + C

• ∫sec(13Π − 2x)tan(13Π − 2x)dx

 = ∫tan( − 2x + 13Π)sec( − 2x + 13Π)dx

 = 1 − 2sec( − 2x + 13Π) + C

 =  − 12sec(13Π − 2x) + C

Ok friends, I think enough for this time for this material, f too much would be difficult to understand.

Good bye, see you again with me in other time,...hopefully this material or sample question useful for everything.
