Question
In each group, one word is correctly spelt. Find the
correct word.Solution
The correctly spelt word is "Receive," following the rule 'i' before 'e' except after 'c'.
Evaluate the following:
sin 25° × cos 65° + sin 65° × cos 25°
2 × Tan 30° / (1 + Tan2 30°) equals:Â
If 7sin²θ + 3cos²θ = 4, then find the value of θ?
If x tan 60° + cos 45° = sec 45° then the value of x2 + 1 is

If Sin θ + Cos θ = √2 Cos(90 - θ ), then find the value of Cot θ ?
...If P, Q, R, S are the vertex of a cyclic quadrilateral. Find the value of
`1/sec p` + `1/sec q` + `1/sec r` +`1/sec s`
...If cos² x + sin x = 5/4, then find the value of 'sin x'.
- If √3 cosec 2x = 2, then the value of x:
Simplify: sin 780° sin 480° + cos 120° sin 30°
