We can divide by (cosx)^2 across the identity (sinx)^2 + (cosx)^2 = 1 (which can be derived from properties of the unit circle and a bit of Pythagoras’ theorem) to achieve

[(sinx)^2 / (cosx)^2] + [...

P(J>2) = P(J=0)+P(J=1)     [split it up]

P(X=t)= (V^t)/t!*e^V       where V=4 in this case  [use the formula]

P(J>2) = 4^0/0!*e^4 + 4^1/1!*e^4

          =1/e^4 + 4/e^4  =  5e^-4...

Changing one DNA base will alter one triplet in the DNA code. As each triplet codes for an amino acid this may result in a change to the primary structure of the protein produced. If the changed amino aci...

The Subjunctive is one of the hardest ideas in Spanish, simply because it is not commonly used in English!  The easiest way I find to remember it is to think of WEIRDO!
