If the roots of the equation x^(2) + px+ q = 0 are x^(2) + px+ q = 0 " are " tan 19^(@) and tan 26^(@), then which one of the following is correct ?

If the roots of the equadratic equation x^(2) + px + q = 0 " are " tan23^(@) "and" tan22^(@), then find the value of q - p .

If the roots of the equadratic equation x^(2) + px + q = 0 " are " tan23^(@) "and" tan22^(@), then find the value of q - p .

If the roots of the equadratic equation x^(2) + px + q = 0 " are " tan23^(@) "and" tan22^(@), then find the value of q - p .

If the roots of the quadratic equation x^(2)+px+q=0 are tan 30^(@)" and "tan15^(@) , respectively then the value of 2+q-p is

If int_(0)^( pi)((2x+3)sec x tan x)/(4+tan^(2)x)dx=((p pi+q)pi)/(3sqrt(3)) then p+q=

int((ln(tan x))/(sin x cos x)dxi se q u a lto (a) (1)/(2)ln(tan x)+c(b)(1)/(2)ln(tan^(2)x)+c(c)(1)/(2)(ln(tan x))^(2)+c(d) none of these

If 3 tan 2 x - 4 tan 3 x = tan ^(2) 3 x tan 2 x then x =
