On the same diagram, sketch the graphs of

y=sin 3x & y=cos2x,

for x between 0 degree and 180 degree

sin 3x=cos 2x

in the interval 0 degree less than or equals to x which is less then or equals to 180 degree

Hi, I'm Ai Ling Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths.
I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way.
I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze...
If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
