How do you find tan2x from Sinx?
Similarly, we can write tan2x in terms of sin using the trigonometric identities….We will use the following trigonometric formulas to express tan2x in terms of cos x.
- tan x = sin x/ cos x.
- sin 2x = 2 sin x cos x.
- cos 2x = 2 cos2x – 1.
- sin x = √(1 – cos2x)
How do you solve tan15?
Value of Tan 15
- Tan (15°) can be found if we know the value of sin 15 degrees and cos 15 degrees.
- From the above table, we have the values of tan, sin and cos ratios for 0°, 30°, 45°, 60° and 90°.
- tan (15°) = √3 – 1/ √3 + 1.
- Hence, the value of tan (15°) is √3 – 1/√3 + 1.
- ∴ Tan (15°) = (1.732 – 1)/(1.732 + 1) = 0.2679.
What is the exact value of tan 270?
