Using the quotient rule, the derivative of cos(x) can be calculated in terms of other trigonometric functions by noticing that {eq}sec(x) = \frac{1}{cos(x)} {/eq} so {eq}\frac{1}{sec(x)} = cos(x) {/eq}. Regardless of the choice of method for differentiation, the derivative...

Sin cos tan values are the primary functions in trigonometry. Learn the values for all the angles, along with formulas and table. Also, learn to find the values for these trigonometric ratios.
r . this corresponds to writing your x x and y y in terms of b a b a instead of using the two parameters a a and b b . so it's not really a different parametrisation. then f ( t ) f ( t ) is a rational point on the unit circle if and only if t ...
