<h2>Explanation:</h2>
When we say that an amount of something increases as another amount increases, at the same rate, then we are talking about Direct Proportion. It is also true for an amount of something that decreases as another amount decreases, at the same rate. So "y varies directly as x" can be written as:

In other words:

Where k is the constant of proportionality, and represents the slope of a line that passes through the origin.

we can apply the rules of trigonometry to determine the integral of the function: The exponent is added by 1 and the function is multiplied by the reciprocal of the added power. Hence,
y' = sqrt (1-cosx)y = (2/3) (1 - cos x )^ (3/2) *(x - sin x) y = (2/3) *(x - sin x) (1 - cos x )^ (3/2)
Answer:
The value of given trigonometrical expression is cos²x + sin²x = 1
Step-by-step explanation:
Given trigonometrical expression as :
(
) - sec x = tan x
Or, (
) = tan x + sec x
or, (
) = (
) + (
)
or, (
) = (
)
Now, cross multiplying both side
I.e (cos x) × (cos x) = ( 1 - sin x ) × ( 1 + sin x )
or, cos²x = 1 - sin² x
or, cos²x + sin²x = 1
So, Value of expression is cos²x + sin²x = 1
Hence The value of given trigonometrical expression is cos²x + sin²x = 1 answer
