Take
, so that
and
. Note that this assumes
and so requires
.
Now take
, so that
. Note that for this invertibility condition to hold, we require that
, which means
. But since we already fixed
with the previous substitution, we thus have
, which in turn restricts us to
. So with this substitution, we have
, which gives
Now over the interval
, we have
, which means
, and so the integral is equivalent to
If tan α = 0
α = tan^(-1) 0
α = k π , k ∈ Z ( any integer ), π = 180°
0 · 180° = 0
1 · 180° = 180°
2 · 180° = 360°
3 · 180° = 540°
Answer:
Angles are: 0°, 180°, 360°, 540°.

Answer:
so we have 4/3 divided by 7/4
= 4/3 * 4/7
= 4*4/3*7
= 16/21
