Given: The term sin^2(50°)+cos^2(130°)
To find: Solve the given term.
Solution:
- Now we have given the term sin^2(50°) + cos^2(130°) .
- We know the basic formula of trigonometry:
sin^2 x + cos^ x = 1
- But before that we also have a formula:
sin (180 - x) = sin x
- So, applying this first, we get:
sin^2(180° - 130°) + cos^2(130°)
sin^2(130°) + cos^2(130°) = 1
Answer:
So the value of sin^2(50°) + cos^2(130°) is 1.
