I cannot guarantee that I will be able to finish the book by July. Remember that I have other students and other commitments as well.

As and when I can, I will write up the answers. At other times, other tutors can help, or you may have to attempt a few questions on your own.

Tan-1 (5/3)

Use the tangent inverse function, but in radian form, not degree, since the question needs radians

It’s not the Tan-1 5/3 that’s 2.11

It’s the

Pi - Tan-1 5/3

Which is 2.11
