In this case, each input is associated with a single output.
We may describe it as the collection of the second values in the ordered pairs. List Of IAS Articles. D, which denote their functions and choose the correct one given below. This is why we usually use notation such as. O is the length of the side opposite the angle. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.
The values of trigonometric functions thus are as shown in the table below: For knowing the values of cosec x, sec x and cot x we reciprocate the values of sin x, cos x and tan x, respectively. Best IAS coaching Bangalore. RD Sharma Class 12 Solutions. Try the entered exercise, or type in your own exercise. Identify the input and output values.
In the following table. Is not paired with exactly one element in the range, {1, 2, 3, 4, 5}. Chemistry Calculators.
