Answer:The answer can be simplify by the following steps;
Step-by-step explanation:
Answer:
B. y = tan x and C. y = cot x
Step-by-step explanation:
Range:
range is defined as the set of values that any given function y=f(x), can take for which the x values are defined. It is the value that y can take for the values of x.
Given:
From the given options
the range of tanx and cotx are all real numbers
as the period of tanx and cotx are π
where as range of secx is all real numbers except π/2 + n*π i.e.
(-∞ , -1] U [1 , + ∞)
And range of cscx is all real numbers except n*π i.e.
(-∞ , -1] U [1 , + ∞)
So from the given option:
option B and C are correct while A and D are not !
They are equal.
2/6 = 1/3
1 * 2 = 2
-------
3 * 2 = 6
do you see it?
257,650 rounded to the nearest hundred is 257,700 because it is right at the border (50) we have to round up.
