SO WHAT WE DID ON 2OTH JULY IS START OUR STUDY LESSONS...BUT WE DID NOT START OUR CHAPTER 1 TOO FAST...MS. JOANNE GAVE US SOME LESSONS ON PREREQUISITE SKILLS...THESE QUESTIONS ARE THE SAME ONES THAT WE STUDIED DURING OUR HIGH SCHOOL.. IT'S MERELY A REPEAT ABOUT THE BASICS OF FUNCTION NOTATION, SLOPE AND Y-INTERCEPT OF A LINE AND EQUATION OF A LINE..AND OHH YES..WE DID LEARN SOMETHING NEW, FINITE DIFFERENCES..MS.JOANNE THOUGHT WE HAD STUDIED ON IT LAST TIME BUT NONE OF US HAD..SO SHE TAUGHT US MORE ON THAT..BUT FNITE DIFFERENCE IS A QUITE SIMPLE EXERCISE TO UNDERSTAND I THINK...
WHAT YOU NEED TO KNOW...
FUNCTION NOTATION ~ LEARN HOW TO SUBSTITUTE VALUES OF X INTO EQUATION
SLOPE AND Y-INTERCEPT OF A LINE ~ REMEMBER THE FORMULA Y=MX+C..AND LEARN TO STATE THE GRADIENT(M) AND Y-INTERCEPT(C) FROM AN EQUATION
EQUATION OF A LINE ~ LEARN TO BUILD AN EQUATION FOR A LINE THAT SATISFIES SETS OF CONDITION GIVEN LIKE SLOPE, X-INTERCEPT, Y-INTERCEPT AND POINTS
FINITE DIFFERENCES ~ LEARN TO DETERMINE FINITE DIFFERENCES USING GRAPHIC CALCULATOR AND MANUAL CALCULATION TO FIND OUT HIGHEST EXPONENT OF AN EQUATION AND THE SIGN OF THE LEADING COEFFICIENT...SO IF GET THE 1ST FINITE DIFFERENCE(FD)- LINEAR EQUATION, 2ND FD - QUADRATIC EQUATION, 3RD FD - CUBIC FUNCTION, 4TH FD - QUARTIC FUNCTION, 5TH FD - QUINTIC FUNCTION...AND SO ON
