Hey there! There are two ways.
1. Finger method

The link above has a really easy way to learn the table.
2. A random method whose name I don't know

Also another method.
3.The value of sin theta
Memorize the values of sin theta only. From 0 degrees till 90 degrees. You'll find that cos theta is just the opposite. And then, to find tan theta just divide the sin theta value of the given angle by cos theta value which you just found and BOOM! Tan theta :D
You know what to do next for sec(1/cos), cosec(1/sin) and cot (1/tan)
4. Memorization through practice
This one is my favourite. Keep practicing trigonometry, and it will eventually get stuck in your head.
Hope you understood! Ask me anything in the comments, I'll clarify it for you!
