 # SUM & DIFFERENCE OF TRIGONOMETRIC RATIOS

Understand the formulas of Sum & Difference of Trigonometric ratios, with help of Animation & Visual tools.

We have categorise the topic into 2 sections. Try to understand the difference. When we say, what will be applicable formula for sum of Sin of 30 Degree  & 45 Degree. Here we are talking about 2 options, which are:

(i) Sin (30 + 45)

(ii) Sin 30 + Sin 45

Both of the above are totally different. Difference formulas, will be applicable to both the cases. The formulas will be

(i) Sin (x + y)

(ii) Sin x + Sin y

So, in the below 2 videos, we will understand the formulas &, we will also understand the proof of the same.

## The formulas, that will be covered are:  Refer the below 2 videos to understand the concept in very detail, using Animation & Visual Tools

Hope, you have gained from these videos. Thank you very much for being with CREATA CLASSSES.
