If sin(A+B)=1/2 and cos(A+B)=1/2....find the least values for a and b....and find the most general solution for a and b

6 years ago


Answers : (1)


Dear Bindu,

Ans:- Let A+B=θ

Then according to the given conditions,

cos²θ+sin²θ=(1/4 + 1/4)=1/2≠1 Hence there is no solution

1)prove that (cos x)cos(60-x)cos(60+x) = ¼ cos3x 2)sin 2x -sin5x + sin6x = 0
Use exopansion property of cos(A+B) and apply you will get the answer. Take sin5x on other side and then use the clubbing property of sinA+sinB.

The value of sin(π+x)sin(π-x)cosec^2 x is equal to a)-1 b)0 c)sin x d)none of these
a is the answer... last equation comes as:-(sin^2 (pi)-sin^2 x)/sin^2 x :(0-sin^2 x)/sin^2 x........................(since,sin(pi)=0,so therefore sin^2 (pi)=0) : -1=A option

There`s a line AB whose distance is given and coordinates of A are given as well. How to find the coordinates of B? I tried it by Distance formula but in the end I get a quadratic eqn in x...
Is the equation of any line given?If yes then use parametric form and then solve. You can also bring the coordinates of B completely in terms of x or y.

Simple solution to integral of √sin(x-a)/sin(x+a) as per 12th class syllabus
write sin(x-a) as: sin(x + a – 2a) = sin(x+a)cos2a – cos(x+a)sin2a then think further. and relate to √sin(x-a)/sin(x+a).

Nishant Vora one month ago
z’ = 1+5z and so z’+1 = 5z which means |z’+1| = 5|z| = 10 which means z’ lies on a circle centred at (-1,0) and radius 10. Alternatively you can see that 5z takes all points on the circle...
