Practical Session No. 2

Trigonometry -1

(1) Construct an angle in standard position whose terminal arm passes through 𝐴𝐴(−6,8). Hence find all trigonometric ratios of this angle.

(2) Construct angle of measure 22.50 by bisecting angle of measure 450. Hence find the value of 𝑡𝑡𝑡 𝑡𝑡22.50.

(3) Draw and measure the angle in standard position whose tangent ratio is 713.

(4) Draw and estimate the angle in standard position whose sine ratio is 0.57.

(5) Construct a triangle, the measures of whose angles are 320,580 and 900. Measure the lengths of sides of this triangle. Find 𝑠𝑠𝑠𝑠𝑠 320 and 𝑐𝑐𝑐 320. Hence find the value of sin2320+cos2320.

(6)

 (a) Which is greater, sin(18560)or sin(20190) ? Give reason.

(b) Which of the following is positive ? sin(−3100) and sin3100. Give reason.
