SOLUTION: Please help me solve this equations:
1. {2 sin x-1=0}
2. graph {f(x)=sin(x-2pi)-1}
3. { 40+16 sin x-56=0 for 0<=x<=2pi}
4. {cos x-1 = 0 for 0<=x<= 2pi}
5. Graph { y=sin

Question 330022: Please help me solve this equations:
1. {2 sin x-1=0}
2. graph {f(x)=sin(x-2pi)-1}
3. { 40+16 sin x-56=0 for 0<=x<=2pi}
4. {cos x-1 = 0 for 0<=x<= 2pi}
5. Graph { y=sinx+2 the period is?}
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
1. {2 sin x-1=0}
2sin(x) = 1
sin(x) = 1/2
x = 30 degrees
----------------------
2. graph {f(x)=sin(x-2pi)-1}
-----------------------
3. { 40+16 sin x-56=0 for 0<=x<=2pi}
Not sure what you want here.
---------------------------------
4. {cos x-1 = 0 for 0<=x<= 2pi}
Is the angle "x" or is it "(x-1)"?
---------------------------------
5. Graph { y=sinx+2 the period is?}
Period is 2pi
===================
Cheers,
