Delta as a mathematical symbol usually means "change". It's usually used the same way in physics and chemistry, though it's sometimes used in chemical equations to represent heat.
That equation is, q(Joules) = mass * specific heat ( symbol is C ) * (delta, a triangle) change in temperature That is to say delta means, Temperature Final - Temperature Initial q is a constant and not subject to change as temperature is
< this symbol can also mean less than
Not equal
Delta (of a curve)
delta, or change in diagnosis
That pyramid symbol (or better defined as a triangle as to not get confused with lower mathematics / geometry) simply means a change in something. The actual term is "delta" and it is also known as the derivative of y as seen here: (delta) y / (delta) x. (delta) y / (delta) x would be read as the change in y with respect to x.
Delta - Its the fourth letter of the Greek alphabet, and it is often used in mathematical expressions to represent the change (i.e. the delta) that occurs to a value.
