Solution
2sin2  380 sec2  520 + cos 640 sin 260 + sin2 640 / tan2 280 + cot2  230 – sec2  670 – cosec2  670 = 2 × 1 + cos2  640 + sin2  640 \ tan2 230 + cot2  230 = 2 + 1 / -(sec2 θ – tan2  θ) – (cosec2  θ – cot2  θ) = 3/-1-1 = -3/2         Sin A sec B = 1 If A + B = 900 Sec2  θ – tan2  θ = 1 cosec2  θ – cot2  θ = 1 Sin 2 θ + cos2  θ = 1
80.03% of 120.03 + 119.87 × 8.09 ÷ 5.998 = 2.01 ?
45.22% of (71.9 x 5.01) + 69.97 =?Â
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
What approximate value should come in place of question mark (?) in the following equations?
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
 (108.999)² - (102.001)²=?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
[54.96 × √99.96 – {(25.02/6.84)% of 280.24}]/(3.032 × 19.87) = ?
189.23 + 18.11² + ?³ = √841.76 * 28.94
1111.25 × 9.05 + 2323.23 × 9.05 – 2121.37 × 9.05 = ?
