BAM!!! Mr. Tarrou We are starting one of my favorite topics which is trigonometry. The study of triangles and their rotations around a circle. This…

– WELCOME TO AN EXAMPLE INVOLVING COTERMINAL ANGLES. COTERMINAL ANGLES ARE TWO ANGLES IN STANDARD POSITION THAT HAVE THE SAME TERMINAL SIDE. SO IF WE…

Noticed they have given us no angles inside and we are ask to find an angle. Since we are going to focus on our target…

Friends please make change …..the value of tan(thita) when changed…it should be cot(thita)… I have written it tan…please make change

BAM! Mr. Tarrou. In this video we are going to being doing some more right triangle trigonometry, or in other words we are going to…

Hi, I’m Dr Ian van Loosen from the Department of Maths and Stats at Curtin University. Let’s say you’re a caveman and you see a…

– HERE WE’LL TAKE A LOOK AT DETERMINING THE ANGLE OF ROTATION FOR SEVERAL DIFFERENT ANGLES. SO IF THE ANGLE’S IN STANDARD POSITION, THE INITIAL…
