tan x^(2)-20x+1=0

10x^(2)-20x+1=0

The number of solutions of the equation tan^(2)x-sec^(10)x+1=0" for " x in (0, 20) is equal to

The number of solutions of the equation tan^(2)x-sec^(10)x+1=0" for " x in (0, 20) is equal to

If 20x^2-30x+1=0 , then what is the value of 25x^2+1/(16x^2) ? यदि 20x^2-30x+1=0 है, तो 25x^2+1/(16x^2) का मान क्या होगा ?

Solve for 0^@ le x le 90^@ 3 tan^(2)(2x-20^@)=1

Solve for x : 3tan^(2)(2x-20^(@))=1

if (1+k)tan^(2)x-4tan x-1+k=0 has real roots tan x_(1) and tan x_(2) then

If sec x + sec^(2) x = 1 then the value of tan^(8) x - tan^(4) x - 2 tan^(2) x +1 will be equal to 0
