A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10
86130600000.0 standard form to scientific notation should be equal 8.61306 x 10^10
Use the half angle identity, tan157.5=(1-cos315)/sin315
cos315=cos(-45)=√2/2, sin315=-√2/2
tan157.5=(1-√2/2)/(-√2/2)=(2-√2)/(-√2)=(2√2-2)/(-2)=1-√2
