To evaluate the function f(x) = -a^3 + 6a - 7 at a = -1, we substitute -1 for a in the expression and simplify: f(-1) = -(-1)^3 + 6(-1) - 7 = 1 - 6 - 7 = -12. Therefore, the value of the function at a = -1 is -12. To find the remainder, we can use synthetic division or long ...

Prove that: cos^-1 (4x^3 - 3x) = 3cos^-1 x, 1/2 ≤ x ≤ 1

WebbNow, cos −1(4x 3−3x)=cos −1(4cos 3θ−3cosθ) =cos −1(cos3θ) Since θϵ[0, 3π], Hence, 3θ =3cos −1(x) =a+bcos −1(x) Hence, a=0 and b=3 Now, lim y→abcosy =bcos(0) =b =3 Solve any question of Inverse Trigonometric Functions with:- Patterns of problems > Was this answer helpful?
