Comparison of Stopping Distance and Time for Two Vehicles When the body is moving with a certain velocity and suddenly brakes are applied, then the body stops completely after covering a certain distance, this is called as Stopping Distance. It is the distance travelled between the time when the body decides to stop a moving Read more about Comparison of Stopping Distance and Time for Two Vehicles[…]
Sine of the Difference and Sum of Two Angles 1. sin (A-B) = sinA cosB + cosA sinB Proof: L.H.S: sin (A-B) = sinA cosB + cosA sinB L.H.S sin (A – B) = cos (90 – (A – B)) (since cos (90 – θ) = sin θ) = cos (90 – (A – B)) Read more about Sine of the Difference and Sum of Two Angles[…]

Conditional Identities (Tanθ) – Problems 1. If A + B + C = nπ, n Є Z that TanA + TanB + TanC = TanA TanB TanC. Proof: We have , A + B + C = nπ Tan (A + B + C) = tan(nπ) = tan(π) = 0 , TanA + TanB + Read more about Conditional Identities (Tanθ) – Problems[…]
Equation of a Plane Progressive Wave 1) If during propagation of a progressive wave, the particles of the medium perform Simple Harmonic Motion about their mean position, then the waves is known as a Harmonic progressive wave. 2) Suppose a plane simple harmonic wave travels from the origin along the positive direction of x – Read more about Equation of a Plane Progressive Wave[…]
Conditional Identities Some standard Identities in Triangle: 1. sin2A + sin2B + sin2C = 4 sinA sinB sinC Proof: L.H.S sin2A + sin2B + sin2C (since sinC + sinD = 2sin (C + D)/2 cos (C – D)/2), , , , , , , , , , , , Hence proved 2. cosA + cosB Read more about Conditional Identities[…]
Water Equivalent Water equivalent of a body is defined as the mass of water which would absorb or evolve the same amount of heat as is done by the body in rising or falling through the same range of temperature. It is represented by W. It is the quantity of water whose thermal capacity is Read more about Water Equivalent[…]
