Integral of cos(x), ∫f (x) dx = sin(x) + C) [where C is the constant of integration) Law of Cosines in Trigonometry Thelaw of cosineor cosine rule in trigonometry is a relation between the side and the angles of a triangle. Suppose a triangle with sides a, b, and c and with...
三角函数是具有周期性的,比如终边再原来的基础上再转2k\pi还是与原来的终边重合,且有些角度的三角函数值是有关系的,比如\cos 30^\circ=\sin60^\circ,\sin60^\circ=\sin120^\circ等等。 下面是一些常见的转化公式: 公式一: \begin{array}{l}{\sin (2 k \pi+\alpha)=\sin \alpha(k \in Z)} \\...

The sine function, denoted as sin(x), is defined as the ratio of the length of the side opposite to an angle in a right triangle to the length of the hypotenuse. In other words, sin(x) = opposite/hypotenuse. The sine function is periodic with a period of 2π and takes values betwe...
For a right-angled triangle: let A be the adjacent side that is the side of the triangle next to the angle. let O be the opposite side that is the side opposite to the angle in question \. let H be the hypotenus (the sloping side). Then by definition: sin 78...
