How to remember trigonometric ratios values easily?

It is a very easy to remember all the trigonometric values.
U Just have to remember the values of sine function and that's all.
Now
(I) For cosine function just reverse the values of sine function, {as for basic values sinx = cos(90-x)}. For example:- sin60° = cos30° = √3/2
(II) For tangent value find cosine and sine value and just do sinx/cos x . For example sin30°= 1/2 and cos 30° = √3/2 so tan30° = sin 30°/cos30° = 1/√3
(III) And for remaining functions like cot , secant and cosecant just make 1/tanx , 1/cosx and 1/sinx.
Hope this will help u to remember as it did for me.
But if u still are facing problems don't worry as u will remember it as the time passes away and you study more complicated maths in life. :)
Best Of luck with my trick. :)
