" 34.In Fig."5.47" ,the value of "cos phi" is "

In Fig.5.47 ,the value of cos varphi is (FIGURE) (5)/(4) (b) (5)/(3)(c)(3)/(5) (d) (4)/(5)

In Fig. 5.47, the value of cosvarphi is (FIGURE) 5/4 (b) 5/3 (c) 3/5 (d) 4/5

If (sin^2 phi+3sin phi+2)/(cos^2 phi)=1 , where -90^@< phi <90^@ , then what is the value of (cos 2 phi+sin3 phi+cosec2 phi) ?

If tan((pi)/(4)+phi)=(1)/(3) ,then the value of cos2 phi is

If 2 cos theta=x+(1)/(x) and 2 cos phi=y+(1)/(y) then the value of cos (theta+phi) will be

If cos theta =(4)/(5) " and cos " phi =(12)/(13) " where " theta " and " phi both lie in the fourth quadrant find the values of (i) " cos " (theta + phi) " " (ii) " sin " (theta -phi) " ' (iii) " tan " (theta + phi)

If cos(theta-phi) , cos(theta) , cos(theta+phi) are in HP, the the value of cos(theta)sec(phi/2) is

If sin theta sin phi - cos theta cos phi+1 =0 then the value of 1+ cot theta tan phi is-
