HEY EVERYONE, I'M BACK HERE AGAIN WITH YOU ALL AFTER A LONG AND BUSY WEEKEND. WELL, WE STUDIED ON HOW WE SHOULD SOLVE TRIGONOMETRIC EQUATIONS TODAY. IN A WAY,TODAY'S LESSON MIGHT BE REVIEW FOR MOST OF YA..CAUSE WE HAVE STUDIED THESE BEFORE..ONLY IN DEGREE FORM. HOWEVER, WE'RE LEARNING THROUGH RADIAN PROCESS RIGHT NOW..
THERE'S NOT MUCH FOR ME TO POINT OUT IN THIS CHAPTER. TRIGONOMETRIC EQUATIONS CAN BE SOLVED ALGEBRAICALLY BY HAND OR GRAPHICALLY WITH TECHNOLOGY. THEY ARE OFTEN MULTIPLE SOLUTIONS. MAKE SURE YOU FIND ALL SOLUTIONS ACCORDING TO THE GIVEN DOMAIN IN THE QUESTIONS. SOMETIMES, THE SOLUTION YOU GET MIGHT BE BIGGER OR SMALLER THAN THE GIVEN DOMAIN, SO MAKE SURE YOU DON'T INCLUDE THEM. AND ONE MORE THING IS, QUADRATIC TRIGONOMETRIC EQUATIONS CAN OFTEN BE SOLVED BY FACTORING.
SO TO FURTHER ENHANCE YOUR UNDERSTANDING ON THIS FAVORITE SUBTOPIC OF MINE IN THIS CHAPTER, I HAVE INCLUDED A VIDEO FOR YOUR VIEWING..CHEERS!! :)
