A BJT is said to be operating in the saturation region if

The breakdown voltage of a transistor with its base open is BV_CEO with emitter open is BV_CBO, then

If $$L\left\{ {f\left( t \right)} \right\} = {{2\left( {s + 1} \right)} \over {{s^2} + 2s + 5}}$$ then $$f\left( {{0^ + }} \right)$$ and $$f\left( \propto \right)$$ are given by ___________.

The third term in the taylor's series expansion of $${e^x}$$ about $$'a'$$ would be ________.
