What is the output of the following program? print("Hello World"[:
SyntaxError
Simplify: $sin^2 x + cos^2 x = $
Simplify: $sin^2 x + cos^2 x = $
- $tan^2 x$
- 1 (correct)
- 2 sin(x) cos(x)
- None of these
Study Notes
Trigonometric Identity
- The equation ( \sin^2 x + \cos^2 x = 1 ) represents a fundamental Pythagorean identity in trigonometry.
- This identity holds true for all angles ( x ) and is widely used in various mathematical applications.
Programming Syntax
- The code snippet
print("Hello World"[[:represents an incomplete slice operation in Python, leading to a syntax error. - Proper string slicing in Python requires specifying both start and end indices, hence the absence of a complete syntax would cause the program to fail.
Options for Question 1
- None of these: Incorrect; the correct answer is a well-established identity.
- 1: This is the correct simplification of ( \sin^2 x + \cos^2 x ).
- 2 sin(x) cos(x): This expression equals ( \sin(2x) ) but is not related to the given equation.
- ( \tan^2 x ): Incorrect; this does not relate to the Pythagorean identity.
