� � � � � � �I learned on how to find the reference angle is in order to find the reference angle, First find the equivalent angle . And the equivalent angle is the angle that is greater than or equal to 0 degrees and less than 360 degrees. Once you find the equivalent angle, you are ready to find the reference angle.And for me it is one of the lesson I really understand that we had discussed.
� � � � � � �Second Topic I like is Arc Length. Arc Length is a function of the circumference of the circle which is� / 2pi. The arc length of an arc intercepted by a central angle of�� �radians on a circle of radius r is given by��it is the formula we will used to find the missing variable. And in my own understanding about arc length it is a conventional to let the letters symbolize the length of an arc, which is called arc length. And the circumference of a circle is an arc length, ratio to the diameter is the basis of radian measure of the central angle which that are subtends.
� � � � � � � For me this lesson about the arc length is easy because I easily understand it than the other lesson that we discussed. And in this lesson we easily find the length of the arc using the formula�. And I only say in this lesson about Arc Length is the easier lesson for us than other. Circumference is like an our life did you know why because sometimes we are in Down, Middle, or sometimes at the Top. We need to do our best every time. Third Quarter is Super Exciting I'm happy.
