If sinƟ = x and secƟ = y , then tanƟ is (A) xy (B) x/y (C) y/x (D) 1/xy - Bzziii

If sinƟ = x and secƟ = y , then tanƟ is 

(a) xy 

(b) `"x"/"y"` 

(c) `"y"/"x"`
 
(d) `"1"/"xy"`




(A) xy 

Explanation:

Given,

sinƟ = x and,

secƟ = y

∴ `"1"/"cosƟ"`= y

cosƟ = `"1"/"y"`

Now, tanƟ = `"sinƟ"/"cosƟ"`

= `\frac{"x"}{\frac{"1"}{"y"}}`

= xy
