If `trianglephi` denotes phase difference, then explain the meaning of the following two equations.
(i) `triangle phi=(2pi)/T triangle t and (ii) triangle phi=(2pi)/lambda x`

The difference between the two acute angles of a right angled triangle is (2pi)/5 radians. Express the angles in degrees.

In a triangle ABC, prove that the ratio of the area of the incircle to that of the triangle is pi:cot(A/2) cot(B/2) cot(C/2)

Two waves are passing through a region in the same direction at the same time . If the equation of these waves are y_(1) = a sin ( 2pi)/(lambda)( v t - x) and y_(2) = b sin ( 2pi)/( lambda) [( vt - x) + x_(0) ] then the amplitude of the resulting wave for x_(0) = (lambda//2) is

Find the phase difference betwee the two progressive wave. y_(1)=A sin ((2pi)/(T) t-(2pi)/(lambda) x) and y_(2)=A cos ((2pi)/(T) t-(2pi)/(lambda)x)

The equation vec(phi)(x,t)=vec(j)sin ((2pi)/(lambda)vt)cos ((2 pi)/(lambda)x) represents

What do we represent a wave using the equation, y= A sin(omegat+ triangle phi)? What is the meaning of each symbol ?

If the difference between the two sides of a right-angled triangle is 2 cm and the area of the triangle is 24 cm^(2) , find the perimeter of the triangle.

The equation. Delta x. Deltap ge h//4 pi shows

Two medians drawn from the acute angles of a right angled triangle intersect at an angle pi/6dot If the length of the hypotenuse of the triangle is 3u n i t s , then the area of the triangle (in sq. units) is sqrt(3) (b) 3 (c) sqrt(2) (d) 9
