Oh . Ok. But when do I need to change the mode to rad and when do I keep it normal ????

hey cos (2x π/4) is equal to 0, u get 0.9996 is because ur calculator is in degree mode mate

Thanks for the video .. but wanted to ask in the first question . When u reached the part where u have to find C. .. how did u assume cos2@ = 0???????? I tried it on my calculator many time but never got zero . Cos 2(π/4) is equal to cos (π/2) which is equal to 0.9996242169

I have a lot of free time over the next few days so will be working very hard to produce as much as possible. As I know an exam is coming very soon. Two more videos on integration then I will start vectors and complex numbers.

Will you be dropping a video for complex number? Before the 18th
