Sin Cos Tan Values (Formula, Table & How to Find)
For starters, we will focus only on sine and cosine and then fall back on the fact that tan(θ) = sin(θ)/ cos(θ). Our goal is to fill in the following table based on what we know: θ sin(θ) cos(θ) 0° 30° 45° 60° 90° 45° is a good place to begin. ... Thus we have the critical conversion formula…

x = cos (, and y = sin (. Simple geometry (right triangles and pythagoras' formula) will help locate values for some angles such as 30(, 45( and 60(. Using symmetry on the unit circle you can find values for angles that are multiples of 30(, 45( and 60(. Your calculator will assist you for other angles. First quadrant values for cos ( and sin (.
