We will also discuss the common logarithm logx and the natural logarithm lnx. ISBN 978-0-983373-1-1 color ISBN 978-0-9833973-0-4 b w. That exponent is called a logarithm.
Cosine cotangent and cosecant are found by using the entry on the opposite page.
If x is the logarithm of a number y with a given base b then y is the anti-logarithm of antilog of x to the base b. Eg since 1000 10 10 10 10 3 the logarithm base. The natural log represented by ln is the base-e log where e is the constant 2718. Logarithms of the latter sort that is logarithms.
