Remembering values of standard angles can be difficult. But with the method shown below you can easily remember the values of standard angles.

First of all write down the values of standard angles.

So, by this way you can easily remember values of standard angles.

Values of Cosec, Sec and Cot can be found by taking inverse of Sin, cos and tan respectively for the given angle.
