The domain is the set of all possible x values, for this problem it would be negative infinity to positive infinity. The range is the set of all possible y values, for this problem it would be -2 too +2
It is equal to 1.8It is equal to 1.8It is equal to 1.8It is equal to 1.8

It is the same. So they are equal
If you do not know what y is equal to then you can not evaluate this. If it is equal to zero then y is equal to 6/5.
cos2x + 2sinx - 2 = 0 (1-2sin2x)+2sinx-2=0 -(2sin2x-2sinx+1)=0 -2sinx(sinx+1)=0 -2sinx=0 , sinx+1=0 sinx=0 , sinx=1 x= 0(pi) , pi/2 , pi
2sinx+1 equals 0
The same as the period of y = sin x. This period is equal to (2 x pi).
2sinx - sin3x = 0 2sinx - 3sinx + 4sin3x = 0 4sin3x - sinx = 0 sinx(4sin2x - 1) = 0 sinx*(2sinx - 1)(2sinx + 1) = 0 so sinx = 0 or sinx = -1/2 or sinx = 1/2 It is not possible to go any further since the domain for x is not defined.

4 sin2x = 1. Then, (2sinx)2 = 1, 2sinx = ±1, and sinx = ±½. Whence, x = 90° or 270°; or, in radians, x = π/2 or 3π/2.
3*sin2x = 2*sinx +1
take out the constant -2 then take the intergral of cosx this will give you sinx your answer is -2sinx
You also need an equation for y in order to convert to rectangular form.
The information you provided in your question does not include an =. Therefore it is not an equation; it is an expression
First find the derivative of each term. The derivative of any constant is zero, so d(1)/dx=0. To find the derivative of cos2x, use the chain rule. d(cos2x)/dx=-sin(2x)(2)=-2sin(2x) So the answer is 0-2sinx, or simply -2sinx
