This is a free lesson from our course in Trigonometry
In this lesson, you'll introduce tangent of an angle and slope of a line and its relationships. It explains that
the tangent of an angle with measure
, which is made by
the line AB with the xaxis, is equal to the slope of the line AB. So,
m represents slope, which is equal to tan
.
m = tan
= length of segment AC/length of segment CB
Once you go through the instructor's explanation in the video above, it'll be easy
for you to understand how the above graphs of sine and cosine function will be sketched.
