Question

need a help guys .maths trigonometry ❤plz help class 10 but do in ur own handwriting .thq ❤

Answer 1

L.H.S

(1/cos@+sin@/cos@-1)/(sin@/cos@-1/cos@+1),

(1+sin@-cos@)/(sin@-1+cos@),

[sin@+(1-cos@)]/[sin@-(1-cos@)],

[sin@+(1-cos@)]²/[sin²@-(1-cos@)²],

[sin²@+(1-cos@)²+2sin@(1-cos@)]/[sin²-(1+cos²@-2cos@)],

[sin²@+1+cos²@-2cos@+2sin@-2sin@cos@]/[sin²@-1-cos²@+2cos@],

[sin²@+cos²@+1-2cos@+2sin@-2sin@cos@]/[1-cos²@-1-cos²@+2cos@],

[1+1-2cos@+2sin@-2sin@cos@]/[2cos@-2cos²@],

[2-2cos@+2sin@-2sin@cos@]/[2cos@-2cos²@],


[1-cos@+sin@-sin@cos@]/[cos@-cos²@],

[(1+sin@)-cos@(1+sin@)]/[cos@(1-cos@)],

[(1+sin@)(1-cos@)]/[cos@(1-cos@)],

(1+sin@)/cos@,

(1²-sin²@)/cos@(1-sin@),

cos²@)/cos@(1-sin@),


cos@/(1-sin@),

then

L.H.S=R.H.S
