Question

if sin x = 3/5 & x is 2nd quadran then find tan xt​

Answer 1

tan xr value is sinx =3/5, cosx=4/5,tanx =3/4

Answer 2

Answer:

according to all STC means in first quadrant all are +ve , in second quadrant sin and cosec are +ve , in third quadrant tan and cot are +ve , and in fourth quadrant cos and sec are +ve

sin in 2nd quadrant it is +ve so the inverse of sin cosec is 5/3

formula of tan is sin /cos

sin²x +cos²=1

9/25+cos²x=1

cos²x=1-9/25. = 16/25

cosx=4/5 but in second quadrant cos is -ve so cosx =-4/5

so tan is sinx/cosx = -3/4
