Hi,
Can someone help me to do these problems?
1).If tan(θ+α)-(3+2√2)tanθ = 0,
Prove that, sin(2θ+α )= √2sinα
2).Prove that, cos⁻¹x-sin⁻¹x= π/6
Hello, Malsha!
Could that be: . This is not true!2) Prove that: cos⁻¹x-sin⁻¹x= π/6
That is: .
We have: .
Hence, the two angles are in this triangle.Code:* * β* 1 * * * * * * * α * * * * * * * * x
And we see that the two angles are complementary: .
So their sum is a constant, but not their difference.
