The hypotenuse (H) is the longest side of the triangle opposite to the 90 degree angle. The other two sides are known as the base (B) and perpendicular (P) side. The formula to find the hypotenuse is the square of the hypotenuse equals the sum of the squares of the base and the ...

For example, to find the derivative of sine, we need: and we let dx go to zero. This is tricky to work on directly, but using the sin(a+b) formula we have As dx goes to zero, cos(dx)=1 (zero angle is full width), so we have: And as dx goes to zero, sin(dx...

Simplify the expression by using a double-angle formula. (2 tan 22)/(1- tan^2 22) Write as an algebraic expression not involving any trigonometric functions: \sin(\tan^{-1} u). Use the fundamental identities to simplify the expression. sin phi(csc phi - sin phi...
But what if you are reflecting off of some weirdly rotated platform, or the vector <2, 3>, or a line at a 45 degree angle? In either case, you can use the formula below to accomplish reflection: Let R be the vector result of the reflection Let N be the normal vector...
求助编辑百科名片三角函数是数学中属于初等函数中的超越函数的一类函数。它们的本质是任何角的集合与一个比值的集合的变量之间的映射。通常的三角函数是在平面直角坐标系中定义的。其定义城为整个实数域。另一种定义是在直角三角形中,但并不完全。现代数学把它们描述成无穷数列的极限和微分方程的解,将其定义扩展到...
