Using the tangent subtraction formula: tan(π4−x)=1−tanx1+tanx we can identify that: 1−tan(θ2)1+tan(θ2)=tan(π4−θ2) Conclusion Thus, we have proved that: cosθ1+sinθ=tan(π4−θ2) Hence, the statement is proved. ...
3. Apply the half-angle formula for tangent: The half-angle formula for tangent is: tan(θ2)=1−cos(θ)sin(θ) Here, θ=15∘, so we have: tan(7.5∘)=1−cos(15∘)sin(15∘) 4. Calculate cos(15∘) and sin(15∘): We can use the cosine and sine subtraction formu...
All values of sine, cosine, and tangent of angles with 3° increments are derivable using identities: Half-angle, Double-angle, Addition/subtraction and values for 0°, 30°, 36°, and 45°. Note that 1° = radians. This article is incomplete in at least two senses. First, it is ...
