If `piltalphalt(3pi)/2lt" then "sqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha))` is equal to

If piltalphalt(3pi)/(2) then sqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha)) is equal to

If π<α<(3π)/2 then sqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha)) is equal to

(pi)/(2)ltalphaltpirArr sqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha))=

If π<α<3π2 then sqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha)) is equal to (a) 2/(sinalpha) (b) -2/(sinalpha) (c) 1/(sinalpha) (d) -1/(sinalpha)

If pi,t h e nsqrt((1-cosalpha)/(1+cosalpha))+sqrt((1+cosalpha)/(1-cosalpha)) is equal to 2/(sinalpha) (b) -2/(sinalpha) (c) 1/(sinalpha) (d) -1/(sinalpha)

Givent that pi/2 lt alphaltpi then the expression sqrt((1-sinalpha)/(1+sinalpha))+sqrt((1+sinalpha)/(1-sinalpha)) (A) 1/(cosalpha) (B) - 2/(cosalpha) (C) 2/(cosalpha) (D) does not exist

If cotalpha=(15)/(8) , then ((2+2sinalpha)(1-sinalpha))/((1+cosalpha)(2-2cosalpha))=?

If 0^(@)ltalphalt90^(@) , then solve the equation (sinalpha)/(1-cosalpha)+(sinalpha)/(1+cosalpha)=4 .

If alpha=pi/7 then find the value of (1/cosalpha+(2cosalpha)/(cos2alpha))

If alpha=pi/7 then find the value of (1/cosalpha+(2cosalpha)/(cos2alpha))
