Lecture #9

Today, we completed the discussion of trigonometric integrals, which are integrals with integrands being powers of cosine times powers of sine; or powers of tangent times powers of secant. Other type of trigonometric integral may be converted to the above

HW#3 partial solutions and sketches

Check out the course files section. I made sketches on nearly each problem in HW #3, plus full solutions to some general area / volume problems. (Written in a rush, may have mistakes.) Hope it helps midterm 1 prep.

Thank you for the help.

This could be a worse day for me if you guys weren’t quick enough to point out the mistakes. Hope I’ll recover soon from bad shape. I intended to cover more on trigonometric integrals that could be solved by substitution

Lecture #8

Today, we reviewed our list of applications of integrals and worked on 3 special examples. For each problem, the process of translating a sketch and problem description into integrals is EXACTLY the same as before. However, the integrals we got

Lecture #6

Today, we’ve covered the geometric problem of area bounded by two curves (Section 6.1). The key points we want area in the usual sense, not “signed area” which is the default output of a definite integral the Riemann sum method
