By applying the formula of trigonometric function the right hand side will
be equal to right hand side which is 1-
/
=cos2x.
Given: 1-
/
=cos2x.
Taking right hand side first which is cos2x.
We know that cos2x=
Now we will solve the left hand side of the equation give which is
1-
/
=1-
/1+
[secant square x minus tangent square x is equal to 1]
By putting both values left hand side and right hand side we will find our solution which is :
1-tan^{2}x/1+tan^{2}x=1-
/1+
.
Hence proved

Answer:
5n + 2 > 3 (If you're writing the equation)
n > 1/5 (If you're solving for n.
Step-by-step explanation:
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+y=1
3x-y=4
-------------
y=3x-4
2x+3x-4=1
5x-4=1
5x=1+4
5x=5
x=5/5
x=1
y=3(1)-4=3-4=-1
Answer:
50.24
Step-by-step explanation:
Area = r^2 x 3.14 (pi)
Radius = 8 ÷ 2 = 4
4² = 16
16 x 3.14 = 50.24
Area = 50.24 cm ²
The correct answer would be 41
