If `p_1,p_2,p_3` are the principal values of for trigonometric equations

If p_(1),p_(2),p_(3) are the principal values of following trigonometric equations I) Sintheta=-1//2 II) Costheta=-sqrt(3)/(2) III) Tantheta=sqrt(3)-2

If (2p-1), 7, 3p are in AP, find the value of p.

If p+1/p=2 then the value of p^2-1/p^2 is :

What is the value of p in the given equation 8(2p-5)-6(3p-7)=1?

2(p+1)+8(p-1)=5p What value of p is the solution of the equation above?

For what value of p the pair of linear equations (p + 2)x – (2p + 1)y = 3(2p – 1) and 2x – 3y = 7 has a unique solution.
