  • means its centre at2,1 and radii 4.it is at adis.from 2 so area of one triangle from quadilateral is 8.so another is also a right angled triangle  so its area 4. so total area 12

If two tangents to the parabola y 2 =4ax from a point P make an angle θ 1 and θ 2 with the axis of the parabola, then find the locus of P if cosθ 1 cosθ 2 =λ...
 
 
Let the equation of tangent in slope form be y= mx + a/m Let point P be (h,k) hence this point will satisfy the line there fore: k = mh + a/m or mh^2 - km + a = 0 (a quadratic in 'm' which...

No. of solutions of x,where x belongs to [0,2pie] and satisfies the equation, |sin a| +|cos a | = |sin x| where a is any real number. (Plz provide solution with explanation)
 
 
Solution: 2 Consider the left hand side of the equation and find its range. To do that let’s take its square ( |sin a| +|cos a |) 2 =sin 2 a+cos 2 a+|sin 2a| = 1 + |sin 2a| Since 0...
