Question

Sinx secx =1 x lies in 2nd quadrant find sin x,secx

Answer 1

Answer:

Sinxsecx=-1

sinx/cosx=-1

tanx=-1

x=135

now, sinx=sin135=1/√2

secx = sec135=-√2

I hope this will help u :)

Answer 2

Sinx secx =1

tanx = 1

x = tan tan^-1(135°)

X = 135°

sin135°=cos45° = 1/sqrt2

sec(135) = - cosec 45° =-sqrt2
