Answer:
"Different representations (written descriptions, tables, graphs, and Linear functions may be used to represent and generalize real situations. Slope and y-intercept are keys to solving real problems involving linear relationships. "
Step-by-step explanation:
The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values.
Answer:
The answer is tan²Ф + 1 = sec²Ф
Step-by-step explanation:
∵ sin²Ф + cos²Ф = 1 ⇒ ÷ cos²Ф both sides
∴ sin²Ф/cos²Ф + cos²Ф/cos²Ф = 1/cos²Ф
∵ sin²Ф/cos²Ф = tan²Ф
∵ 1/cos²Ф = sec²Ф
∴ tan²Ф + 1 = sec²Ф
