^_^ Trigonometry ^_^
1) We know that,
2) Now, 15°
We also know that,
Using above Identity of Double angles :
Let tan(15°) = x
Negative value of quadratic formula is rejected ,since tan(a) is positive when 'a' is acute angle.
Therefore, Value of tan(15°) = 2-√3
Since, We got value of one trigonometric angle and we can easily find other trigonometric ratios.
^_^ Try to find other trigonometric ratio as your own.
You will get,
3)
We know that,
Let tan(22.5°) = x,
Negative value of quadratic formula is rejected ,since tan(a) is positive when 'a' is acute angle.
^.^
Now, we can easily find other trigonometric ratios.
We get,
4)
We also know that,
Let tan(7.5°) = x :
Negative value of quadratic formula is rejected ,since tan(a) is positive when 'a' is acute angle.
Hence,
We Can easily find other trigonometric ratios.
