A) Similar to what you see in your textbook, you can generally omit the multiplication symbol as you answer questions online, except when the symbol is needed to make your meaning clear. For example, 1⋅105 is not the same as 1105. When you need to be explicit, type * (Shift + 8) to insert the multiplication operator. You will see a multiplication dot (⋅) appear in the answer box. Do not use the symbol ×. For example, for the expression ma, typing m ⋅ a would be correct, but mxawould be incorrect.

ma=....

B) Enter the expression 2cos2(θ)−1, where θ is the lowercase Greek letter theta.

2cos2(θ)−1 =.....

c) Enter the expression asin(x)+15, where asin(x) is the inverse sine function.

asin(x)+15 =....

D) Enter the expression (√(2gΔy)/m), where Δ is the uppercase Greek letter Delta.

(√2gΔy/m)=........

E) Enter the expression N0e−λt, where N0 is N-naught (an N with a subscript zero) and λ is the lowercase Greek letter lambda.

N0e−λt=....
