No, and we may take a counterexample to see why. If y=x^5+5/3x^4, dy/dx=5x^4+20/3x^3, d2y/dx2=20x^3+20x*2=20x^2(x+1). Setting this to 0 will give us the candidates for a POI, but not all these numbers wil...

The period between childhood and adulthood is a time of great transition and turbulence with regards to changing bodies, close relationships, and expectations. It is one of the most rapid phases of develo...

We can use the cosine rule to determine the lenght of XY.
XY² = 10²+8²-2108cos ZXY² = 100+64-180(1/8) = 144XY = 12
