Trigonometry Quiz 2 Trigonometry quiz for class 10 1 / 10 1. The value of the (tan2600 + sin2450) is 1/2 3/2 1 7/2 2 / 10 2. sin2600 – 2 tan 450 – cos2300 = 2 –2 1 –1 3 / 10 3. What happens to the value of cos θ when increases from 0º to 90º? cos θ decreases from 1 to 0. cos θ increases from 0 to 1. cos θ increases from 1/2 to 1 cos θ decreases from 1 to 1/2 4 / 10 4. sin θ - cos θ sec θ - tan θ sec θ + tan θ sin θ + cos θ 5 / 10 5. 1 cos² θ - sin² θ sin² θ cos² θ 6 / 10 6. In the given figure, AOB is a diameter of a circle with centre O, The value of tanA.tanB will be 1 2 3 4 7 / 10 7. If tan5θ = 1 then θ is equal to 9º 90º 45º 30º 8 / 10 8. If tan(A + B) = √3 and tan(A- B) = 1/√3 , A > B , then the value of A is 45° 60° 90° 30° 9 / 10 9. The value of (1 + tan2 θ) (1 - sin θ ) (1 + sin θ) = 0 1 1/2 2 10 / 10 10. If tanA = cotB, then the value of (A + B) is 90° 120° 60° 180° Your score isThe average score is 0% 0% Restart quiz
