�� How does the value of sine and cosine of complementary angles relate

Cosine is co added onto sine. Basically, cosine is the sine function moved over 90degrees or pi/2 (pi/2 on a unit circle is 90 degrees)

Sin(x)=cos(x+90) <--degrees
Sin(x)=cos(x+pi/2) <--radians

The above two equations for converting them is called a cofunction identity. There's many more identities to convert sines, cosines, tangents, cosecantes, secantes, and cotangents between each other. This is taught to you in PreCalculus.

How do you find how many times greater a power is for example how many times greater is 2 to the power of 30 than 2 to the power

Subtract the exponents. 30 - 18 = 12.
2^30 is 2^12 times greater than 2^18.

If sin x = .42, what is cos x?

horrorfan [7]

$We\ know:\\\\\sin^2x+\cos^2x=1\to\cos^2x=1-\sin^2x\to\cos x=\sqrt{1-\sin^2x}\\\\\sin x=0.42\\subtitute\\\\\cos x=\sqrt{1-0.42^2}=\sqrt{1-0.1764}=\sqrt{0.8236}\approx0.91$
