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.
Find out the general formula for the tangent vector and unit tangent vector to the curve specified by r → (t) = t 2 i → + 2 sin t j → + 2 cos t k → . Solution First,
Level Curves or Contour Curves Another topic that we should look at is that of level curves or also known as contour curves. The level curves of the function z = f (x, y) are t
Calculate the area and perimeter of a square: Calculate the area and perimeter of a square with w = 5´ and l = 6´. Be sure to involved units in your answer. Solution:
Evaluate following limits. Solution : Let's do the first limit & in this case it sees like we will factor a z 3 out of the numerator and denominator both. Remember that
what is a liter
Example of Multiplying Decimals: Example: 0.45 x 10 = 4.5. Same, while multiplying a decimal through 100, 1000, and 10,000, move the decimal point to the right the similar
