Quandaries and Queries
I have some questions about pre-calculus.
I tried the problems, and here is what I have so far:
(1) (cos(x))^2=1-(sin(x))^2, so substituting,
(2) I don't know where to start here.
(4) starting with the original equation, tan(x)*csc(x)
(5) I don't know
where to start here.
I can help with a few of your problems.
For problems 5, 6 and 7 draw a right triangle and write down what you know. For example for problem 6.
In the diagram sin(t) = 24/25, so tan(arcsin(24/25)) is the tangent of t. Use Pythagoras' Theorem to find the length of the third side of the triangle, and then find tan(t).
