1.	State whether the following are true or false. Justify your answer.sin θ = cos θ for all values of θ.
Answer» False. sin 30° = \(\frac{1}{2}\) cos 30° = \(\frac{\sqrt 3}{2}\) sin 30° ≠ cos 30° But sin 45° = cos 45° = \(\frac{1}{\sqrt 2}\)

State whether the following are true or false. Justify your answer.sin θ = cos θ for all values of θ.

Answer»

False.

sin 30° = \(\frac{1}{2}\) cos 30° = \(\frac{\sqrt 3}{2}\)

sin 30° ≠ cos 30°

But sin 45° = cos 45° = \(\frac{1}{\sqrt 2}\)
