For a right angle triangle, cosine of an angle is the ratio of base or adjacent side to hypotenuse of triangle.

Whereas the law of Cosine is used to calculate the side of that triangle, whose one angle and two sides are known. Sine and cosine are primary trigonometric functions; however, each function has its own importance in resolving mathematics problems. It represents a mathematical curve depicting a repetitive oscillation motion similar to a sine function.

It represents a mathematical curve depicting a repetitive oscillation motion similar to a cosine function. Difference between Sine and Cosine Wave. Key Difference: Sine and cosine waves are signal waveforms which are identical to each other.
