Answer:
The only difference is that for any positive value of 'x' g(X) and h(X) will be same and for any negative value of 'x' g(x) and h(x) will be different.
Step-by-step explanation:
Given
|x| is modulus of x so modulus makes negative value as psoitive
for example
now we will solve for the above
For
and
Now for
and
so for positive value it is same and for negative value it is different
Answer:
The value of Cos (-Ф) .
Step-by-step explanation:
Given Trigonometric function as :
sin( - Ф ) =
- sin Ф =
So, sin Ф =
Now, as sin Ф =
So , =
So, perpendicular = 3
And hypotenuse = 5
Now,<u> From Pythagoras Theorem</u>
Base ² = Hypotenuse² - Perpendicular²
Or, Base ² = 5² - 3²
Or, Base ² = 25 - 9
Or, Base ² = 16
∴ Base =
I.e Base = 4
Now, Cos Ф =
So, Cos Ф =
Now , Since
Cos ( - Ф ) = Cos Ф
So, Cos ( - Ф ) = Cos Ф =
Hence The value of Cos (-Ф) . Answer
