Take L.H.S sin2A+sin2B/sin2A-sin2B
= sin2A+sin2B/sin2A-sin2B
Put
[sinC+sinD = 2sin(C+D)/2cos(C-D)/2]
[sinC-sinD = 2cos(C+D)/2.sin(C-D)/2]
= 2 sin(2A+2B)/2 cos(2A-2B)/2 / 2 cos(2A+2B) sin(2A-2B)
= sin(A+B).cos(A-B)/cos(A+B).sin(A-B)
= sin(A+B)/cos(A+B) . cos(A-B)/sin(A-B)
= tan(A+B).cot(A-B)
= tan(A+B).1/tan(A-B)
= tan(A+B)/tan(A-B)
∴ Hence we proved sin2A+sin2B/sin2A-sin2B=tan(A+B)/tan(A-B)
Answer: I will give you hints but not straight up answers kay?
Step-by-step explanation:
In fact, you have undoubtledly encountered non-integer exponents in the past, though you might not have been aware of it at the time! The simplest non-integer power is the square root. Let us review what we do when we take the square root of a number. In taking a square root of 4 for instance, we ask ourselves what number(s) can by multiplied by themselves once in order to give 4? The answer is: well 2 × 2 gives 4 and so does (-2) × (-2). Thus, +2 or -2 raised to the power of 2 gives 4. So the square root of 4 is equal to ±2 (the notation "±" means "plus or minus"). Thus, if Sqrt is to denote the process of taking the square root we have:
22 = 4
Sqrt(22) = Sqrt(4)
2 = Sqrt (4)
Answer:
32
Step-by-step explanation:
36-4
Use Pythagorean theorem
Answer:
x=1
2x+3=5
-3 -3
now the three gets canceled and 5-3 is 2
2x=2
now divide 2 on both sides
2x÷2=2÷2
x=1
