/cos 90 0 =undefined we learned about sin theta 0 degrees value along with other degree values here, this far. also, derived the value for cos degree and tan degrees with respect sin degrees. in the same way, we can find other trigonometric ratios like sec, cosec and cot. based on ...
这些函数的倒数分别被称为余割(\displaystyle\csc或cosec)、正割(\displaystyle\sec)和余切(\displaystyle\cot): \displaystyle\cscA=\frac1\sin A=\fracca, \displaystyle\secA=\frac1\cos A=\fraccb, \displaystyle\cotA=\frac1\tan A=\frac\cos A\sin A=\fracba. 正弦定理 勾股定理 角 代数 单位...
Cosec \Theta = \frac{h}{p} Sec Function Sec is the term used for secant. Sec of an acute angle of the right-angled triangle is defined as the ratio of the longest side (hypotenuse) to the length of the side on which the angle is drawn. Sec \Theta = \frac{h}{b} Cot Function:...
