Some equations are true for all allowed values and are then called Identities Example: sin (−θ) = −sin (θ) is one of the Trigonometric Identities Let's try θ = 30°: sin (−30°) = −0.5 and −sin (30°) =
Solve P equals 2l plus 2w for l. So this right here, this is just the formula for the perimeter of a rectangle. Perimeter is equal to 2 times the length plus 2 times the width. But they just want us to solve this

Amazing app! I love it cause it can give me answers to math Problems (More Fun in Math, and Less stress!) I Also have a idea for your next Change for this app (For the Graphs) If you Scan a Graph or image that is a Graph should have a Answer too so it's less confusing for the Younger Students, Thank You for Making this App.
