How to Find Trigonometric Ratios of 45 Degree
Hi friends ! Once again !
So far we have learned many things about trigonometry. We know very good about the fundamental trigonometric ratios. We learned
to find the angle, to find the value of given trigonometric expressions, trigonometric verifying problems and so on !
Now our trigonometric learning journey has been a little been changed ! Previously we use to take the reference angle variables
like x, y , A, B ,theta, beta etc . Now we will take some standard angles like 30 degree, 45 degree, 60 degree, 90 degree etc.
In this videos we are going to find out the trigonometric ratios of 45 degree angle. So ready for the lesson ! Did you take your pen and notebook ? Great !
So ! Close your eyes and command your mind before learning that you are going to learn a very nice topic in trigonometry and
you will understand it very nicely !
Okay ! you can watch in full zoom mode of the video to view in full screen- see the option at bottom of the right side corner.
Let’s learn together now !
So, how was it friend ? I hope you understand how to find the trigonometric ratios of 45 degree geometrically by making isosceles right angled triangle.
