**Remembering Trig Sum and Difference Formulas YouTube**

Formulas for right triangles. The most important formulas for trigonometry are those for a right triangle. If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side... One way of recalling the values of trig. derivatives is to remember all the ones that start with c are NEGATIVE. Another thing to remember is that cot and tan are related respectively to csc and sec. As you can see cot and csc both start with c, so that is another way to remember.

Remember the derivative of sin and cos, and then you can get the derivative of everything else using the power rule and product rule. (Hint: write tan(a) as sin(a)cos -1 (a) where the -1 is a multiplicative power, not a function inverse, and the product and power rules work out well.) how to return a product on snapdeal The easy way to remember the Difference and Sum of Cubes Formula is to remember that the ﬁrst factor looks like you just remove the cubes.
