Trigonometry
Titel: When you need to solve a triangle, in other words you need to find a side or an angle in a triangle, what is the starting point?
Keywords:
Angle of elevation | angle of depression | opposite | adjacent | hypotenuse | equations with fractions
ID: 4399/10-Trigonometry
Titel: Find the size of an unknown angle in a triangle, when two sides are given
Keywords:
opposite | adjacent | tan | second function | shift
ID: 4401/10-Trigonometry
Titel: We need to find the area of a quadrilateral by solving two triangles so that we can have lengths of sides to use for the bases and the perpendicular heights
Keywords:
area of triangle | opposite | adjacent | rounding
ID: 4403/10-Trigonometry
Titel: We get exposed to the inverse trigonometric ratios by studying their roles in a normal triangle
