FURTHER MATHEMATICS SSS2 THIRD TERMWEEK 4MECHANICS (VECTOR GEOMETRY)ContentSCALAR OR DOT PRODUCT OF TWO VECTORSThe scalar or dot product of two vectors a and b is written as a.b and pronounced as (a dot b). Therefore, a.b =|a| |b| cosƟ dot is defined as a.b = a b cos Ɵ where Ɵ is the angle between vectors a and bIf a = a1 I + a2j and b = b1 I b2jThus a .b = (a)1bi ii + ab2j I 1 + 2 bi I h +a2 b2 j

(dy/dx = 3x2 + 2)then the antiderivative of 3x2 + 2 = x3 + 2x Thus, integration is the reverse process of differentiation and is denoted by the symbol ∫.If dy/dx = xn , then ∫ dy/dx = xn+1 + Cn + 1 (n ≠ -1)where c is the arbitrary constant.

FURTHER MATHEMATICS SSS2 THIRD TERMWEEK 8INTEGRATION (INDEFINITE INTEGRAL, DEFINITE INTEGRAL AND AREA UNDER CURVEContentThe process of reversing differentiation is called Integration. If dy/dx = 3x2, then y could be x3, as the derivative of x3 is 3x2.We say that x3 is an integral of 3x2 with respect to x. The symbol for integration sign is given by ∫ . The expression to be integrated is put between the ∫ sign and dx.∫ 3x2 dx could be x3Since differentiating any constant gives zero, the following also have derivation 3x2.

A bivariate data involves two variablesTYPES OF SCATTER DIAGRAM:Linear positive correlation.A positive correlation between two variables x and y means that in general, an increase in x is accompanied by an increase in y. The regression line has a positive slope.
