## Zoom Math 400 Makes Trigonometry Easy

See what Zoom400 can do!

 Simplify a Trig Expression Prove a Trig Identity Solve a Triangle Evaluate a Recursive Sequence

With a registered copy of Zoom Math 400, you can:

• Type trig problems the way they look, without extra parentheses.
• Easily type angles in degrees or radians, without complicated menus.
• Type csc, sec, and cot.
• Simplify complicated trigonometric expressions.
• Solve equations that include trig functions.
• Show step-by-step proofs of trig identities using TRACE.
• Solve triangles using the Law of Sines or the Law of Cosines.
• Calculate the points where two nonlinear equations intersect.
• Define a recursive sequence and calculate a term in the sequence.

Best of all, Zoom Math 400 can show the steps of most solutions, so you can see exactly how to do the math!

## Zoom Math 400 Makes Algebra Easy

Even without a Registration Key, Zoom Math 400 makes calculations easy. Fractions look like fractions and exponents look like exponents. Everything looks right. An unregistered copy of Zoom400 works just like an unregistered copy of Zoom200 or Zoom300: It does everything App4Math can do, plus a little bit of graphing and a little bit of algebra.

After you buy a Registration Key, Zoom Math 400 can do everything that any previous Zoom Math product can do. It can show problems in correct math notation like App4Math, graph equations like Zoom Math 100, solve Algebra 1 problems like Zoom Math 200, and solve Algebra 2 problems like Zoom Math 300.
