Question

Express cos 63° + cot 59° -Sec 47 in terms of trigonometric ratios of angles between 0 and 45°
​

Answer 1

Step-by-step explanation:

From the figure, you should be able to see that cos75∘ is in fact smaller than either cos45∘ or cos30∘, so it cannot be true that cos75∘ is equal to cos45∘+cos30∘.

Answer 2

Answer:

sin 27° + tan 31°- cosec 43°
