2 questions on trigonometry. Each opens in the question browser with its memo.
Evaluate two reciprocal-ratio expressions to two decimal places — (cos 28°)(cot 28°) and sec(40° + 10°). Then, in right-angled triangle ABC with sides 6, 8 and 10, work without a calculator: write sin α, cot α and cos α as exact fractions, and calculate the size of θ.
Trigonometry on the Cartesian plane. With OM = 13 cm and M(x; 12) at an acute angle θ, use Pythagoras to find x, determine cos θ, and show that (sin θ)(sin θ) + (cos θ)(cos θ) equals 1. A final expression is evaluated without a calculator.
