sin stands for sine.cos stands for cosine. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine').Co-functions have the relationship sin@ = cos(90-@) However, the trig function csc stands for cosecant which is completely different from cosine.As you might have noticed, cosecant has a 'co' written in front of ''secant'.

This creates an equation that is a polynomial trig function. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with. As a reminder, here are the trigonometric identities that we have learned so far:An identity, in mathematics, is an equation that is true for all possible values. (It is always true regardless of the values that are substituted into the equation.) A trigonometric identity is an equation that involves trigonometric functions and is true for every single value substituted for the variable (assuming both sides are "defined" for that value) You will find that trigonometric ...In each of the identity calculators, given any function value and quadrant of theta, the exact value and calculation process will be displayed.
