I am taking MATH 111 at Clark College spring quarter and was wondering what is a great way to prepare for it? I can probably find a College pre-algebra book from the library and brush up on that. What do you recommend? I want to get straight A's next quarter. Gonna take Physics, Algebra, ENGL 102, and a p.e. class. Load of hard courses huh?

Verify the identity: tan(π/4-θ) = (1-tanθ) / (1+tanθ)
Now I hate these proofs. It is easy in the exercise but I have this take home quiz which is only 5% of my grade but I would love to learn to do these professionally could anyone help me do these? I have the remaining questions below 
Verify the identity: Cos(4x) - Cos(2x) / 2sin(3x) = -sin(x)
Verify the identity: 2cos(2x-2) / sin(2x) = cot(x) - sec(x)Csc(x) - tan(x)
Write an expression that is equivalent to Sec(2tan-¹x) Yet that does not use trig functions. Assume that the variable represents a positive value.
Give all radian solutions to tan²5x = 3
Solve 1+Cos(2x) = 2Sin²(2x) for x, where 0≤x<2π
Give all degree solutions to cos(7x)cos(2x)+sin(7x)sin(2x)=½
Eliminate the parameter t: x=4+8Csc(t) y=7-8Cot(t)
Verify the identity [Cos(x/2)-sin(x/2)]² = 1-sin(x)
I would be forever grateful if someone could help me here. Everyone around me can't even count to ten and work as dishwashers ;p
