Q.
- Remove Parentheses: \(3\sen x + ) - (\sen x - [\sen x - ])\ First, we need to remove the parentheses, starting with the innermost set. \(3\sen x + ) - (\sen x - \sen x + ) = \sen x + - \sen x + \sen x -
- Group Like Terms: 3\sen x + 1 - 3\sen x + 5\sen x - 4 Now, we group the like terms, which are the trigonometric terms with \sen x and the constant terms. (3\sen x - 3\sen x + 5\sen x) + (1 - 4)
- Combine Like Terms: 3\sen x - 3\sen x + 5\sen x + Simplify the expression by combining like terms.0\sen x + 5\sen x +
- Simplify Expression: 0\sen x + 5\sen x - 3Since 0\sen x is , it can be removed from the expression.5\sen x - 3
