pls tell me how can i solve ( inclination of a line 45 degree ) , the question is
if the inclination of a line is 45 degree then what is the slope ?
thx for your help
special angles that you should memorize the six trigonometric function of by heart. You can't learn all the degrees. That wouldn't be practical (nor possible). You might also familiarize yourself with the unit circle. But, if you're just starting out, look at the tutorial I suggested.
