Question

can anyone help me how can i do the trignometric maths? I am just getting confused with those identities.....

Answer 1

you can learn all the formulas and try question u can do that

Answer 2

Dont....
for remembering sin values.. Just write sin 0= 0/4 sin 30=1/4 sin 45=2/4          sin 60=3/4,sin 90=4/4 and whole root them all.

the identities involving sec, tan cosec etc....the 2 ratios to be subtracted have same denominator..... eg. sec^A-tan^A=1 = (1/cos^A)-(sin^A/cos^A)=1
