GRAPHS OF OTHER TRIG FUNCTIONS

GRAPHS OF OTHER TRIG FUNCTIONS. We are interested in the graph of y = f ( x ) = tan x. Start with a "t" chart and let's choose values from our unit circle and find the tangent values. Tangent has a period of ? so it will repeat every ?. y. would mean there is a vertical asymptote here.

CIRCLES

CIRCLES. The standard form of the equation of a circle with its center at the origin is . r is the radius of the circle so if we take the square root of the right hand side, we'll know how big the radius is.

Sum and Difference Formulas

Sum and Difference Formulas. Often you will have the cosine of the sum or difference of two angles. We are going to use formulas for this to express in terms of products and sums of sines and cosines. The formulas are:.

TRIGONOMETRIC IDENTITIES

TRIGONOMETRIC IDENTITIES. Remember an identity is an equation that is true for all defined values of a variable. We are going to use the identities that we have already established to "prove" or establish other identities. Let's summarize the basic identities we have. RECIPROCAL IDENTITIES.
