The sine function (sin x) can only have values in the range between 1 and -1. Perhaps you can work it out from there.
sin(x) + cos(x) = sqrt(2) · sin(45°+x)

If tan 3a is equal to sin cos 45 plus sin 30, then the value of a = 0.4.
sin7x-sin6x+sin5x
When tan A = 815, sin A = 0.9999992 and cos A = 0.0012270 so that sin A + cos A*cos A*(1-cos A) = 1.00000075, approx.
SQRT(3)/4 - 1/4
The differentiation of sin x plus cosx is cos (x)-sin(x).
The exact value of sin 22.5 is 0.382683432
what is the value of sin 75 degree
what is the value of a 100 sin sundert mark
The only variable on the right hand side is sin(x). The maximum value of sin(x) is 1. So, the max value of 3sin(x) is 3*1 = 3 and so, the max value of 3sin(x) + 2 is 3+2 = 5.
The proof that sin2A plus sin2B plus sin2c equals 4sinAsinBsinC lies in the fact that (sin 2A + sin 2B + sin 2C) = 4 sinA.sinB.sinC.
[sin - cos + 1]/[sin + cos - 1] = [sin + 1]/cosiff [sin - cos + 1]*cos = [sin + 1]*[sin + cos - 1]iff sin*cos - cos^2 + cos = sin^2 + sin*cos - sin + sin + cos - 1iff -cos^2 = sin^2 - 11 = sin^2 + cos^2, which is true,
sin(40o) = 0.6428
