Trigonometric questions are math problems that involve angles and ratios using trigonometry. They usually test how well you understand relationships between angles and sides of triangles.
1.Solve the equation 2 cosθ= √3 in the range 0o≤θ≤360o
2. Solve for x in the equation -3xsinx=1 in the range 0o≤θ≤360o
3. Solve for x in the equation sin2x = 0.25 for 0o≤θ≤360o giving your answer in πc
4.$$\text{Given that } tan \theta = \frac{sin \theta}{cos \theta}$$
5. solve the equation 2 sinθ = cosθ in the range 0o≤θ≤360o to the nearest whole number
6. Calculate without using log table:
$$\frac{sin 225^o \times cos360^o \times tan 30^o}{sin 120^o \times cos 315^o}$$
7.Triangle ABC is inscribed in a circle as in figure below. AB = 9.2cm, AC = 7.9 and BC=4.4cm
