Answer:
Step-by-step explanation:
<u>Take some reference points on the graph of f and g:</u>
- f(2) = 1, g(2) = 2
- f(4) = 2, g(4) = 4
- f(8) = 4, g(8) = 8
<u>According to the numbers above we can state:</u>
So the value of k is 2
Answer:
y = x + 1 which is marked by the broken line
1)
LHS = cot(a/2) - tan(a/2)
= (1 - tan^2(a/2))/tan(a/2)
= (2-sec^2(a/2))/tan(a/2)
= 2cot(a/2) - cosec(a/2)sec(a/2)
= 2(1+cos(a))/sin(a) - 1/(cos(a/2)sin(a/2))
= 2 (1+cos(a))/sin(a) - 2/sin(a)) (product to sums)
= 2[(1+cos(a) -1)/sin(a)]
=2cot a
= RHS
2.
LHS = cot(b/2) + tan(b/2)
= [1 + tan^2(b/2)]/tan(b/2)
= sec^2(b/2)/tan(b/2)
= 1/sin(b/2)cos(b/2)
using product to sums
= 2/sin(b)
= 2cosec(b)
= RHS
