Question

The position vector of a particle at time t is . Find the condition imposed on α by requiring that at time t = 1, the acceleration is normal to the position vector.

Is this solution right or not

Find  the absolute maximum and  minimum value of a function f given by f(x)= 2x^3-15x^2+36x+1 on the interval (1,5)

you have little mistakes in solutions so correct it

Sin^-1[✓x✓(1-x^2) -x✓(1-x)] in simplest form

write the set a = x 4x-5 29 x € n in the roster form

3cos^2 (a) = 1       .. *correction
