Question
Select a suitable figure from the Answer Figures that
would replace the question mark (?) from question figure.Solution
The upper left element becomes the lower outer element, the outer part of the upper right element becomes the lower –inner element and the symbol inside the upper right element remains in its place, the lower –inner element becomes the upper left element, the lower outer element becomes the outer part of the upper –right element.
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
If A lies in the first quadrant and 6 tan A = 5, then the value of 8 sin A−4 cos A / cos A+2 sin A is :
If x+ 1/x = 2cosθ, then the value of x³+ 1/x³ is
If sin5A = cos(2A+20°), then what is the value of A? Given that 5A is an acute angle.
If sec a + tan a = 3, find the value of sin a.
If sec(2A + B) = 2 and cos(A + B) = (1/√2) , find the value of {sec 2B + tan (A + B) } given that 0o < A, B < 90o
- If sin(A + B) = 1/2 and cos(A + 2B) = √3/2, where 0° < A, B < 90°, then find the value of tan(2A).
If α means +, β means -, ɣ means x, θ means ÷ then 30 θ 10ɣ 5α 10β20 is
If cot8A = tan(A+8˚), find the value of A? Given that 8A and A+8 are acute angles.
