Both the function "cos x" and the function "sin x" have a maximum value of 1, and a minimum value of -1.

the value of sin(x) lies between -1 to +1. the approx value of sin(x)/x = 1 when x tends to 0 & sin(x)/x = 0 when x tends to infinity.
The value of sin(1) is 0.
Theata = Tan^-1(Ay/Ax) Theata = 75.7 deg
Sin(x) has a maximum value of +1 and a minimum value of -1.
sin x can have any value between -1 and 1; therefore, 3 sin x has three times this range (from -3 to 3).

-- The sin of 1 degree is 0.01745. (rounded) -- The sin of 1 radian is 0.84147. (rounded) -- The sin of 1 grad is 0.01571. (rounded)
If you know that "sin(x)sin(x)=1", this must mean that just sin(x)=1 or -1, since sin(x) can take any value between -1 and 1, but both must be the same in order for "1" to be the product.Now, plot a regular sin(x) curve, and find all the possible points where sin(x)= 1 or -1. These are your x values.
If y = sin x:x can take on any value, so the domain is the set of real numbers.y can take on values between -1 and 1 (including the extremes); so the range is -1
It is: sin(90) = 1
sin(3π/2) = -1
type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine
