sin(π ÷ 4) × sqrt(16)
2.828427
Step-by-Step Solution
1
Substitute π = 3.141593: sin(3.141593/4)*sqrt(16)
2
Simplify terms inside sin(): sin(0.785398)*sqrt(16)
3
Evaluate sin(0.785398) = 0.707107: 0.707107*sqrt(16)
4
Evaluate √(16) = 4: 0.707107*4
5
Evaluate remaining arithmetic (0.707107*4) = 2.828428
Concepts & Definitions
Trigonometric Functions
Trigonometric functions (sine, cosine, tangent) map an angle to ratio components on a unit circle. In CalcOS, inputs for trigonometric functions are computed based on active DEG/RAD mode.
Square Root
The square root of a number x is a value y such that y² = x. For example, √16 is 4 because 4 × 4 = 16.
