Q. Show basic Trigonometric Functions?
Ans.
There are six trigonometric functions and they can be defined using a right angle triangle. We first label each side according to the angle we are interested in. Consider the angle in the diagram. The horizontal side is adjacent to the angle, so we label this side adjacent. The vertical line is opposite from the angle , so we label it opposite. The hypotenuse is always the side across from the right angle.
The three most important trigonometric functions are sine, cosine and tangent. They can be defined with abbreviations as follows:
Since these are extremely important functions, it would be very helpful if you learn these ratios. You may be able to remember them better if you consider the ‘word' SOH CAH TOA.
If the roots of the equation (a-b) x 2 + (b-c) x+ (c - a)= 0 are equal. Prove that 2a=b+c. Ans: (a-b) x 2 + (b-c) x+ (c - a) = 0 T.P 2a = b + c B 2 - 4AC = 0
