Question

Write the following trigonometric ratio using figure 1) sin lambda 2) Cos thita 3) tan lambda ​

Answer 1

B- cos teta

A-sin lambda

90 angle;tan lambda

Answer 2

1)sin lambda

sin =perpendicular /hypo.

sin =there is no lambda in figure

sorry

2) cos thita =AD/AB

3) tan lambda =perpendicular /base

=CD/AD
