These functions are abbreviated as sin, cos, and tan respectively. These functions are particularly useful when dealing with right triangles and the unit circle. The trigonometric functions can help solve for missing sides and angles in a triangle. Often, the Pythagorean Theorem is also useful to...
好紧,你使用的编程语言中应该已经包含了许多三角学相关内置数学函数。也许是全局的,也许在 Math 类内,在此篇中,你会和名为 sin、cos、tan 的这些东西打交道。这几个函数代表了正弦、余弦、正切,这些你在初中的时候肯定学过了(译者:九年制义务教育的肯定学过,看看谁是漏网之鱼…) ...
{eq}\sin(arc\tan(x)) {/eq} Inverse trigonometric function: The opposite of trigonometric functions is known as inverse trigonometric functions. It is denoted by ?arc? or ?(trigonometric function)?1?. In a right triangle, if two side lengths are identified then the unknown measure of an ...
csc(α) = 1/sin(α) Secant is the reciprocal of the cosine sec(α) = 1/cos(α) Cotangent is the reciprocal of the tangent cot(α) = 1/tan(α) Trigonometry in a right triangle From the previous analysis, we can obtain some valuable formulas that relate the angle of a right triangl...
