wishboy SG SEC 3 LEVEL topics tested Polynomials and Partial Fractions Modulus Function Coordinate Geometry Trigo Functions Simple Trigo Identities and Equations Those highlighted in red and bolded are the ones i need help in u can help me by telling me wad to take note of when doing the questions thanks
wishboy SG i will take amaths even if i fail continuously and yes now sec 3s very pitiful, learn partial fractions
^tamago^ SG Polynomials and Partial Fractions F(a) = (x-a)Q(x) + R If F(a) = 0, then (x-a) is a factor because F(a)=(a-a)Q'(x)=0Q'(x)=0 Practice one or two can liao. Partial Fractions Know what each denominator leads to what numerators (x+k) leads to A/(x+k) (x²+k) leads to (Bx+C)/(x²+k) (x+k)² leads to two parts A/(x+k) and B/(x+k)² (x+k)³ leads to three parts A/(x+k), B/(x+k)² and C/(x+k)³ (x+k)^n leads to n parts Compare their coefficients and form equations to solve.
^tamago^ SG Identities: 1. Memorise the tables, but I must say, practice makes u remember them much better. Especially multiple angle questions! 2. LHS=RHS, you can work from RHS or use pencil and try to find a midpoint linking the two
^tamago^ SG Yes. Or simply simplify and take out a number? But a pure partial fractions qn wun ask that. A irreducible denominator of Ax²+Bx+C will mean a numberator of Bx+C.
^tamago^ SG sian tonight i wun be free... u all last min i got no time to give tips leh. got questions need explanations faster type out we can sort it out for u now.
HyuugaNeji SG still got one more year to O level. take it easy man. In one year, you can do many things.
