Question

How to learn trigonometry formulas easily and fastly ?

Answer 1

there is one easy trick to learn this first u learn sin full and reverse there order u will get cos and then divide sin by cos u will get tan and rest u can easily find

Answer 2

just remember like this:-
√0/4...√1/4...√2/4...√3/4...√4/4
0°...........30°.....45°...60°........90°
sin
cos
tan
cot
sec
cosec
remember that sin=1/cos
tan=1/cot
sec1/cosec
for zero degree do √0/4..and so on for other values... you will get the line of sin then run it opposite you will get cos then divide it
like, sin0=0 cos 0=1 so
0/1 and you will get tan then again run it opposite to get cot and so on to get cosec... i hope it helps
