The value of
If we consider only the prin ciple values of th e inverse trigonometric functions then the value of
The number of real solutions of
⇒ x^{2} + x+1 = 1⇒ x(x +1) = 0
⇒ x = 0, – 1 are the only real solutions.
for then x equals
On both sides we have G.P. of infinite terms.
If 0 < x < 1, then
The value of x for which sin (cot^{ –1} (1+ x)) = cos (tan^{–1} x) is
The value of cot
The principal value of
The principal value of
= sin^{ –1} (sin π / 3) = π / 3
∴ (d) is the correct answer..
where the inverse trigonometric functions take only the principal values, then the correct option(s) is (are)
