Give all radian solutions to cos7xcos2x+sin7xsin2x=1/2. How do I do this?
A belt connects two pulleys with radii 2.7 inches and 4.5 inches. The larger pulley is rotating at 20 rpm. A) What is the angular speed of the larger pulley, in radians per minutes? B)...
A paper come is unfolded to reveal that it is formed using a sector of a circle with radius 3 inches. If the arc length around the top of the cone is 7.7 inches what is the surface area of the outside...
SPECIAL ANGLES. can someone help me evaluate this for me? thank you.
1)f(x)=(3x2+5)(2x-1) 2) f(x)=6x-11/8x+1 3) f(x)=(5x-2)(2x+3)/x-4 4)f(x)=(8x+3)2 5) f(x)=√¯8-5x 6) f(x)-6x(7x-1)2 7)...
I need to write a piecewise function to represent the cost for staying at the hotel and i have no idea how to do it.
this honestly has my mind boggled. I haven't been in school for 3 years and I am completely lost. I need an explanation of how to work this problem out or as much as you can tell me. thank you.
sec x=sin2x/sinx - cos2x/cosx
This is a best question for all .
1. Multiply and simplify: sin x(cot x- csc x) 2. Factor and simplify: csc² xsec² x-csc² x 3. prove the identity: cos² x+1/sin² x= 2csc² x-1 4...
