First to find the stationary points, you have to differentiate the equation of the curve y, to give you (dy/dx) = 10 - 4x - 6x^2After differentiating the equations, the points at which the curve is statio...

Arithmatic term n, Un= U1+(n-1)d. Where U1 is the first term of the sequence and d is the common difference. U5=U1+4d=6. U1=6-4d. Sum of arithmatic terms up to term n, Sn=n/2(2U1+(n-1)d). S12=12/2(2(6-4d)...

Integrating xⁿ gives you xⁿ⁺¹/(n+1).Integral of 2x⁵ is 2x⁶/6 = x⁶/3. The integral of 7x³ is 7x⁴/4.-(3/x²) can be rew...
