Math Problem Statement
Solution
The image contains a mathematical exercise with the instruction: "Pritaikyk sumos arba skirtumo sinuso arba dvigubojo kampo sinuso formulę" which translates to "Apply the sine sum, difference, or double angle formulas for sine."
Let's break down each part of the task:
-
g) :
- No specific formula is given to expand this further. However, you could use the sine of multiple angles formula, but that may not be needed here.
-
h) :
- There isn’t a specific sum, difference, or double angle formula directly related to , so this might require additional context for further expansion.
-
i) :
- This expression is of the form , which can be rewritten as .
- Applying the formula: .
-
j) :
- This is the sine of a difference: . This is a known identity from trigonometry.
-
k) :
- This is the sine double angle formula: .
- Applying this formula: .
-
l) :
- Again, using the sine double angle formula: .
- Here: .
Would you like more details on any specific step, or do you have further questions? Here are five questions to expand on the material:
- How would you apply the double angle formula for cosine?
- What is the identity for ?
- Can you express in terms of only and ?
- What is the sum-to-product identity for ?
- How would you solve using a double angle formula?
Tip: Remember that for trigonometric identities, the sine of complementary angles like can simplify expressions significantly!
