If tan a=1/root 3 and b=root3 find sina cosb

Answer»

ANSWER:

tan a =  SIN a /COS a = 1/root3 /root3

sin a = 1/rt3

cos b = rt3

if you are ASKING sin a * cos b

                            1/rt3 * rt3 = 1

if you are asking sin a and cos b indivisuallly

then sin a = 1/rt3

cos b = rt3

hope it helps !!!!!!!!

plz MARK me as brainliest!!!!!!!!!!
