How To Use Half Angle Formula - The half angle formula for tangent is helpful when you need to determine the exa.. When using the half angle formula for sine and cosine learn whether the result is positive or negative. Putting in 150 for x, and using the plus sign since 75 is in q1, we get sin(75) = sqrt((1+sqrt(3))/2). Given the tangent of an angle and the quadrant in which the angle lies, find the exact values of trigonometric functions of half of the angle. Instead of using a sum or difference formula, we can now say that 15 degrees is half of 30 degrees, which is an angle on the unit circle! For example, you might not know the sine of 75 degrees, but by using the half angle formula for sine, you can figure it out based on the known value of sin(150) = 1/2.

For instance, using some half angle formula we can convert an expression with exponents to one without exponents, and whose angles are multiples of the original angle. It explains how to find the exact value of a trigonometric expres. Csc( 7π 8) = 1 sina = 2 √2 + √2. This trigonometry video tutorial provides a basic introduction into half angle identities.
